Microgrids (MGs) are important because of their ability to provide a "greener" solution to obtain reliable, secure and sustainable electricity from renewable sources of energy. As a MG can be islanded (i.e. disconnected from the main grid), the power quality issues observed are very different when compared to the traditional centralized grid. These issues are of significant importance because the reliability of the grid is impacted by the MG operation. Currently, the typical power quality issues such as total harmonic content and transient stability have been studied only for an ideal voltage source of constant magnitude - assumed to be the distributed generator (DG) connected to a grid. However, under practical conditions, a MG might have more than one DG (Example: solar, wind, diesel generators, and CHP, among others) connected to it and some of these DGs would be subject to varying output throughout the day based on changes in intensity of solar radiation, wind speed, and other environmental factors. The current research takes this into account and examines the efficacy of an existing power quality control strategy for a MG consisting of a stochastically modeled renewable energy source i.e. a solar PV array. A Robust Servomechanism Controller in conjunction with a Discrete Sliding Mode Controller is employed to achieve voltage and current regulation in the MG. Stochastic model of a solar PV array along with a supplemental DC voltage source model have been presented in this research. The solar PV array utilizes actual TMY3 irradiance data for Dayton, Ohio. The supplemental DC voltage source is connected in series with the solar PV output and helps to compensate for the intermittent nature of energy produced by the solar PV array. A cost-based approach to connecting and disconnecting the MG from the utility supply whilst ensuring the maximum use of incident solar energy is also presented in this research. The MG model developed in Matlab Simulink® follows the Consortium for Electric Reliability Technology Solutions (CERTS) architecture for modeling MGs. The examination of the efficacy of an existing control strategy in a MG topology capable of making real-time cost-based decisions is expected to help the practical implementation of MGs.

The increasing penetration of distributed energy resource (DER), distributed generation (DG) and energy storage system (ESS) units in distribution grids leads to the emergence of the concepts of active distribution networks (ADNs), microgrids, and virtual power plants. Nowadays, the use of electronically-coupled distributed energy resources is of great interest that can provide the power of demand side alone or in a small electricity grid. A microgrid is a small-scale power grid in low voltage network that must be able to locally solve energy issues and enhance the flexibility and can operate either in grid-connected or islanded/autonomous mode of operation. To study them, researchers need an appropriate set of methods, software tools, analogous to those exist for large interconnected power systems.The book Microgrids and Methods of Analysis addresses systematic analysis, control/protection systems design, and optimal operation of a distribution system under high penetration of DERs analogous to those that exist for large interconnected power systems. Provides professional guidlines for system planners Explores further research, development, and optimization of existing and new microgrids Addresses analytical methods used for microgrid analysis using advanced research

This chapter addresses the power quality of grid-connected microgrids in steady state. Three different power quality issues are evaluated: the voltage drop, the harmonic distortion, and the phase unbalance. A formulation for an energy management algorithm for microgrids is proposed under the form of a mixed-integer linear optimization including harmonic load flows. It handles both the optimization of the scheduling of all the generation, storage, and load assets, and the resolution of power quality issues at the tertiary level of control by adjusting the levels of certain types of loads within the system. This algorithm is simulated for different scenarios on a conceptual test-case microgrid with residential, industrial, and commercial loads. The results show that the demand-side management mechanism inside the algorithm can adapt efficiently the consumption behavior of certain loads, so that the voltage drop, the voltage total harmonic distortion, and the voltage unbalance factor meet the required standards at every node of the microgrid during the day. It is also highlighted that the microgrid can gradually reduce the purchase of power from the utility grid to which it is connected if the electricity price on the spot market increases.

This book comprises ten articles covering different aspects of power quality issues in microgrids and distributed generation (DG) systems, including 1) Detection and estimation of power quality; 2) Modeling; 3) Harmonic control for DG systems and microgrids; 4) Stability improvements for microgrids. Different power quality phenomena and solution were studied in the included papers, such as harmonics, resonance, frequency deviation, voltage sag, and fluctuation. From a network point of view, some papers studied the harmonic and stability issues in standalone microgrids which are more likely to cause power quality problems. Other papers discussed the power quality problems in microgrids which are weakly interconnected with the main distribution grid. In view of the published papers, there is a trend that increasingly advanced modeling, analysis, and control schemes were applied in the studies. Moreover, the latest works focus not only on single-unit problems but also multiple units or network issues. Although some of the hot topics are not included, this book covers multiple aspects of the current power quality research frontier, and represents a particularly useful reference book for frontier researchers in this field.
