Book excerpt: "With the increasing penetration of renewable energy and other distributed energy resource (DER) systems in distribution networks, the concept of community microgrids has become a desirable option for power system planners. Community microgrids can operate either connected with the centralized grid or isolated, with the benefit of maintaining supply during main grid disturbances, as well as allowing coordinated local control of DERs with and without the support of the main grid. Some components, which are more and more employed in the microgrids such as combined heat and power (CHP) units and electric vehicle charging stations (EVCS), also need to be considered in the planning and operation stages of microgrids, especially the impact of fast charging facilities (FCF) in the community, which entails significant demand fluctuations and high demand peaks.In this thesis, components of a typical community microgrid are modeled. An optimal microgrid asset planning approach is introduced and validated on different scenarios, and parameters whose fluctuation may affect the costs are explored in sensitivity analysis. The input data especially the electrical load data are analyzed, and EVCSs are integrated into microgrid planning processes. As an efficient way to improve energy utilization, demand response is considered in the grid-connected mode of the community microgrid. The work further investigates microgrid economic dispatch based on a decision tree regressor. The decision tree is prevented from overfitting by post pruning, and the multi-output decision tree is used to improve the overall outcome in terms of operational cost performance"--
