The MATLAB/SIMULINK model of a microgrid system is presented in this thesis. The microgrid consists of a converter-fed distributed generator photovoltaic array with maximum power point tracking, a converter-fed battery storage system and a critical load which must be fed power under all circumstances. The microgrid is capable of functioning in either grid-connected or isolated modes of operation. A passive islanding detection method is utilized to switch over from P-Q to V/F control mode, when islanding is detected. The behavior of the microgrid under various faults and other conditions is analyzed. In the second part of the thesis, the need for a wireless communication between the secondary and primary controllers of the microgrid are discussed. Proof of concept results to establish a two-way communication channel for the exchange of information between the controllers are presented.

This dissertation discusses the design and validation of a community-scale DC microgrid architecture that can integrate renewable generation sources by using a distributed control scheme implemented on the microgrid-connected households to mitigate resource variability. The presented system is designed to address the technical and economic challenges of electrifying emerging regions. The levelized cost of electricity (LCOE) is expected to be less than $0.40 per kW-hr over a 15 year horizon. Solar panel costs have steadily declined to make them a very affordable option for distributed generation. However, battery costs have not declined at the same rate. The important figure of merit for microgrids is the efficiency of stored electricity. The architecture presented in this work is shown to minimize losses in stored electricity. Another key feature of the system is the ability to prioritize loads by controlling the power flow of the system. There are three key components of the presented DC microgrid architecture: source converters, fanout nodes, and household power management units (PMUs). The functionality of each of these components and the rationale for their design choices is presented in detail. The PMUs implement a distributed loadline control scheme to mitigate variability in available grid power. The design of the distributed control scheme of the DC microgrid is discussed in detail. The relevance of Lyapunov based analysis towards the large signal stability of grid voltage is also discussed. The first-generation system uses a phase shifted full-bridge converter topology in the PMUs to convert from 380-to-12V in a single stage. Analytical analysis of this topology shows large signal and small signal stability. Transient response of the grid voltages and currents is shown through simulations. Experimental results are presented that showcase the operation and efficiency of system hardware. The second-generation system incorporates a two-stage conversion architecture. The first stage is a 380-to-48V fixed ratio bus converter, which is used to generate a 48V bus for a local cluster of connected households. In the second stage, PMUs utilize a buck converter topology to step down from 48V-to-12V in each household. In addition to simulation and experimental validation of the hardware, a cost analysis is also presented to determine LCOE of system. The second-generation architecture achieves higher efficiency and reduced cost in comparison to the first-generation. Lastly, grounding and protection of the microgrid is discussed in detail. Relevant examples from existing distribution schemes are presented and the rationale behind existing schemes are explored. A grounding and protection scheme that is suited to this dissertation's DC microgrid is presented. The protection scheme is validated throgh relevant simulations and experiments. This work presents a grid topology that is designed to adapt to a changing landscape of solar PV prices and meets the challenge of providing a scalable and low-cost electrification solution. Future efforts in addressing the energy needs of unelectrified regions can build on the work presented in this dissertation.

Utilization of locally available solar energy resources alongside energy storage has emerged as a feasible renewable retrofit to the solely diesel generation-based remote off-grid power systems. The declining cost and improving reliability of photovoltaic (PV) systems, battery energy storage systems (BESS), and power electronics components have contributed to accelerate this trend. The integration of inverter-interfaced Distributed Energy Resources (DERs) such as solar PV systems and BESS along with conventional generation resources significantly increases the complexity of these isolated power grids. Therefore, a hierarchical control system consisting of an energy management system, a power management system and the local controllers of generating and storage resources is often employed to achieve a reliable, secure, and stable power system operation. This thesis develops a real-time simulation model of an isolated power system based on the typical configuration of power systems in remote communities of Northern-Canada. The isolated grid includes a diesel generation plant, a PV system and a BESS with the diesel generators forming the grid under normal operation. Control strategies for the PV system and the BESS under both grid-following and grid-forming modes of operation are discussed. This thesis develops a secondary control layer of a hierarchical microgrid control system to perform power management functions and implements them on a digital automation controller. In order to demonstrate the functionality of the proposed microgrid controller, a Controller Hardware in the Loop (CHIL) simulation testbed is developed. The structure of the testbed, the development and coordination of different levels in the hierarchical control system, and the integration of the IEC-61850 communication for information exchange among various components are discussed. The overall study confirms the effectiveness of the proposed hierarchical controller as well as the applicability of the developed testbed in providing a realistic operation evaluation platform.

Access to affordable sustainable energy is critical for socio-economic human development. Energy poverty is most predominant for populations in rural areas of developing countries, typically the global south. Successful sustainable development requires technology and business innovations to reach these populations and empower them to improve their quality of life. Off-grid electrification strategies and productive energy use (PEU) appliances are a means of increasing energy access, fostering income generating activities. PEU appliances typically range from charging mobile phones to running equipment such as grain milling- or rice husking machines requiring several kilo-watts. Solar home systems (SHS) are an affordable off-grid electrification solution that have reached millions in rural areas. However, SHS has limited tier energy access, whereas microgrid solutions are more often effective in higher energy access but considerably more expensive and difficult to properly size for future energy demands. Swarm electrification is an innovation electrification strategy done by Solshare, that interconnects existing SHS in a community and allows the excess energy of the households SHS to be bought and sold through a bi-directional DC/DC smart controller. A swarm electrified microgrid is scalable and utilizes existing infrastructure while increasing the tier of energy access. The first objective of this thesis was to understand if swarm electrification could benefit from all the same opportunities as SHS for PEU and if it could overcome the limitations. The second objective was to create a robust methodology to economically and technically integrate a small- and a medium-sized PEU appliances into a swarm microgrid. The first objective was accomplished by conducting interviews with stakeholders working directly or indirectly with SHS. Depending on the geographical location of stakeholder operations, the specific incoming-generating benefits, (agriculture, services, industry, etc.) varied, but were all dependent on the capacity of the SHS, which was also repeatedly stated as a critical limitation. Challenges facing SHS for PEUs include financing, component quality, and knowledge of how to effectively use the SHS. The second objective utilized field data from a Selco India designed AC microgrid for Bochai Colony to design a theoretical swarm microgrid. Solshare's swarm simulation program was used to visualize the energy exchange between households in the designed swarm microgrid. The methodology created was applied on the case study of Bochai, firstly resulting in one 750W and one 7.5kW wheat milling machine selected to be analyzed. The PEU appliances were each integrated into the theoretical swarm microgrid and the simulation results were studied. The small-sized appliance was integrated with 334 days of operation and the medium-sized appliance with 44 days. As part of the methodology, the payback period was assessed and both of the PEU appliances had payback periods under 3 years, which is desired for wheat milling machines. Based on the assumptions and data for Bochai Colony, the PEU appliances were economically and technically integrated into the swarm microgrid. In addition to the two main objectives, the capital cost for the AC microgrid versus swarm microgrid as well as affordability for Bochai community was analyzed. Swarm microgrids with new SHS had same cost order of magnitude as the AC microgrid. The cost of microloans for the SHS in the swarm microgrid was more affordable for households, compared to the electricity tariff paid for the AC microgrid, if the household electrical loads consisted of more than 2 LED lights and a mobile phone charger. Therefore, considering the households electrical demand is likely to increase, it would be more beneficial to implement swarm electrification. The PEU appliance simulation results and the high-level economic cost comparison of the swarm microgrid compared to the AC microgrid for Bochai, were shared with Selco India and Solshare. As a result, Selco is considering implementing a wheat milling machine for Bochai community based on the approximate positive results of the payback periods. Furthermore, because of the results highlighting the opportunities of swarm electrification, Solshare and Selco India will look at completing rural electrification projects together in India in the future.
