Methods of generating renewable energy such as through solar photovoltaic (PV) cells and wind turbines offer great promise in terms of a reduced carbon footprint and overall impact on the environment. However, these methods also share the attribute of being highly stochastic, meaning they are variable in such a way that is difficult to forecast with sufficient accuracy. While solar power currently constitutes a small amount of generating potential in most regions, the cost of photovoltaics continues to decline and a trend has emerged to build larger PV plants than was once feasible. This has brought the matter of increased variability to the forefront of research in the industry. Energy storage has been proposed as a means of mitigating this increased variability- and thus reducing the need to utilize traditional spinning reserves- as well as offering auxiliary grid services such as peak-shifting and frequency control. This thesis addresses the feasibility of using electrochemical storage methods (i.e. batteries) to decrease the ramp rates of PV power plants. By building a simulation of a grid-connected PV array and a typical Battery Energy Storage System (BESS) in the NetLogo simulation environment, I have created a parameterized tool that can be tailored to describe almost any potential PV setup. This thesis describes the design and function of this model, and makes a case for the accuracy of its measurements by comparing its simulated output to that of well-documented real world sites. Finally, a set of recommendations for the design and operational parameters of such a system are then put forth based on the results of several experiments performed using this model.

While solar is the fastest-growing energy source in the world, key concerns around solar power’s inherent variability threaten to de-rail that scale-up . Currently, integration of intermittent solar resources into the grid creates added complication to load management, leading some utilities to reject it altogether, while other operators may penalize the producers via rate increases or force solar developers to include storage devices on-site to smooth out power delivery at the point of production. However these efforts at mitigation unfold, it is increasingly clear to parties on all sides that energy storage will be pivotally important in the drive to boost the integration of variable renewable sources into power infrastructures across the globe. Thoughtfully implemented storage technologies can reduce peak demand, improve day-to-day reliability, provide emergency power in case of interrupted generation, reduce consumer and utility costs by easing load balance challenges, decrease emissions, and increase the amount of distributed and renewable energy that makes it into the grid. While energy storage has long been an area of concern for scientists and engineers, there has been no comprehensive single text covering the storage methods available to solar power producers, which leaves a lamentable gap in the literature core to this important field. Solar Energy Storage aims to become the authoritative work on the topic, incorporating contributions from an internationally recognized group of top authors from both industry and academia, focused on providing information from underlying scientific fundamentals to practical applications, and emphasizing the latest technological developments driving this discipline forward. Expert contributing authors explain current and emergent storage technologies for solar, thermal, and photovoltaic applications Sheds light on the economic status of solar storage facilities, including case studies of the particular challenges that solar energy systems present to remote locations Includes information on: chemical storage mechanisms, mechanical storage tactics, pumped hydro, thermal storage, and storage strategies for systems of all sizes—from centralized utilities to distributed generation

This book will provide the technical community with an overview of the development of new solutions and products that address key topics, including electric/hybrid vehicles, ultrafast battery charging, smart grids, renewable energy (e.g., solar and wind), peak shaving, and reduction of energy consumption. The needs for storage discussed are within the context of changes between the centralized power generation of today and the distributed utility of tomorrow, including the integration of renewable energy sources. Throughout the book, methods for quantitative and qualitative comparison of energy storage means are presented through their energy capacity as well as through their power capability for different applications. The definitions and symbols for energy density and power density are given and relate to the volume and weight of a given system or component. A relatively underdeveloped concept that is crucial to this text is known as the theory of Ragone plots. This theory makes possible the evaluation of the real amount of energy that can possibly release out of a given system, with respect to the level of power dependency chosen for the discharge process. From systems using electrochemical transformations, to classical battery energy storage elements and so-called flow batteries, to fuel cells and hydrogen storage, this book further investigates storage systems based on physical principles (e.g., gravitational potential forces, air compression, and rotational kinetic energy). This text also examines purely electrical systems such as superconductive magnets and capacitors. Another subject of analysis is the presentation of power electronic circuits and architectures that are needed for continuously controllable power flow to and from different storage means. For all systems described, the elementary principles of operation are given as well as the relationships for the quantified storage of energy. Finally, Energy Storage: Systems and Components contains multiple international case studies and a rich set of exercises that serve both students and practicing engineers.

Electricity is a perishable commodity; once it is generated it needs to be consumed or stored. Electric energy storage provides both power and energy capacity. Power capacity applications reduce the need for generation, while energy capacity allows for energy consumption to be decoupled from generation. Previous research was done to develop an algorithm for determining the power (MW) and energy (MWh) capacities of a battery energy storage system (BESS) to mitigate the adverse impacts of high levels of photovoltaic (PV) generation. The algorithm used a flat feeder profile, and its performance was demonstrated on the equinoxes and solstices. Managing feeder power leads to fewer voltage fluctuations along the length of the feeder, potentially mitigating load management issues caused by variability of renewable generation and load profile. These issues include lighting flicker, compressor seizing, equipment shut-off, loss of motor torque, frequent transformer tap changes and even voltage collapse due to loss of reactive power support. The research described in this thesis builds on this algorithm by incorporating a smoothed feeder profile and testing it over an entire year. Incorporating a smoothing function reduces the requisite BESS energy capacity necessary to provide firming and shaping to accommodate the stochastic nature of PV. Specifically, this method is used to conduct a year-long study on a per second basis, as well as a one-minute basis, for a distribution feeder. Statistical analytical methods were performed to develop recommendations for appropriately sizing the BESS. This method may be used to determine the amount of PV generation that could be installed on a distribution feeder with a minimal investment in the BESS power and energy capacities that would be required to manage the distribution feeder power. Results are presented for PV penetration levels of 10%-50% of the distribution feeder capacity and show that the use of a smooth feeder profile reduces the required energy capacity by a minimum factor of 10 when compared to a flat feeder profile. Results indicated that it is sufficient to have a one-minute sampling rate, as it provides the necessary granularity to model cloud-induced fluctuations. This method can be applied to any distribution feeder where a load profile and a PV profile are available.

This book proposes the modelling and simulation model of 1 MW grid connected PV based solar power plant on MATLAB Simulink also DVR is modelled with Grid connected PV system along with battery energy storage system in MATLAB/Simulink environment to mitigate power quality problems and the various results are being discussed.In today's world where pollution is also a big problem along with the energy crisis, we need to find ways to meet the energy requirements and at the same tie keeping the environment pollution free and clean. Energy from the sun if harvested with proper techniques can help in meeting energy requirement without causing any pollution. In this book the development of PV array model, their integration & Simulink implementation is described. MPPT i.e. Maximum Power Point Technique Perturb and observe control is beneficial to ensure the output of PV power generation system at the maximum possible power output level. This system consists of PV array of 1 MW power output and Maximum Power Point Technique (Perturb and Observe) is also incorporated in it and then we have Inverter and at last we have the Transformer through which the Power Plant is connected to the Grid. The performance of power plant is also described with several graphs obtained. India has vast area of land which can be utilized for generation of solar energy which is a renewable and modern source of causes no pollution. If administration install a 1 MW grid connected solar PV power plant in any district it will not only fulfil the energy demand of the premises during day time & the extra electricity will be sold to State Power Corporation limited. The income obtained by the selling will help in the improvement of the facilities. During night time the power demand will meet through grid only.Recently, with the development of industries and power electronic devices good electric power quality becomes a major requirement. Every consumer expects a clean and uninterrupted power quality for their sensitive equipment. Due to fast degradation of conventional energy resources, technological advancement is moving towards renewable energy tied grid system such as Photovoltaic energy generation, wind energy generation, Tidal energy generation etc. The major problem with renewable energy generation is variability of output power. When there is flow of energy there will be fault and voltage sag voltage swell fluctuations and other problems which are most common in power system. Voltage sag is one of the most common problems in power system which affects sensitive loads. Sudden change in loads, motor starting and faults in power system are main causes of voltage sag. Custom power devices are implemented to solar power quality problems. These devices use reactive power compensation technique to mitigate power quality problems. In custom power devices DVR and DSTATCOM are most effective. A DVR is a fast-acting custom power device provides effective voltage control to the distribution feeder. Voltage source converter along with battery energy storage system is utilized in DVR for effective operation. If DVR is coupled with battery energy storage system, then complex power injection is also possible in the system. The DVR can instantaneously compensate voltage sag.The contents of this book would be very useful to researchers working in the area of solar grid integration as well as the post-graduate students of Electrical Engineering.

Solar photovoltaic (PV) is the fastest-growing energy resource. The price of energy generation from residential PV has dropped from $0.50 to $0.10 per kWh in the past decade. One challenge with this resource is that the amount of power available depends on the solar irradiance and temperature. Abrupt changes in solar irradiance can cause disturbances to the hosting electricity network and lead to voltage and frequency oscillations. The impact is more severe in a weak grid with high penetration of such resources. Evolving grid interconnection standards are imposing requirements to limit the impacts of these disturbances on the grid. Battery energy storage (BES) technology has also experienced a significant price drop (e.g., from $1100 to $156 per kWh for lithium-ion batteries) in the past decade. Therefore, complementary PV+BES solutions are increasingly considered. A BES of sufficient capacity equipped with appropriate controls can respond to both abrupt and long-term PV power variations. Properly formulating the problem and developing efficient control systems is crucial. These define the scope and objective of this research. This research develops two BES solutions. In the first one, the BES is co-located with the PV and connects to its dc output terminals. The BES controller ensures that the PV+BES system exhibits a desirable power ramp rate set by the user. In the second solution, the BES is not co-located with the PV. It detects the disturbances from their signatures on its locally measured signals and takes proper actions. An approach based on capacitor emulation combined with a droop mechanism is developed and optimally designed to provide dynamic and static supports. The BES can respond to the disturbances from more than one PV system and non-PV sources, such as load disturbances. The dissertation presents detailed modeling and control of the BES system. Optimal control techniques are developed to ensure robust and fast responses. For the simulation study, the proposed BES systems are implemented in a hybrid dc/ac study system and the effect on both dc and ac subsystems are investigated. The real-time results obtained by implementing the proposed controllers on laboratory-scale hardware prototypes are also presented.
