The application of HOMER software as powerful software for optimal residential microgrids is presented. The residential microgrid’s optimal planning procedure with required input data, objective functions, and design constraints are explained. The system structure and relevant components are introduced. In this chapter the projection of residential microgrids is discussed. Optimal planning or design of microgrids is accomplished to achieve the minimum price with the highest reliability and lowest environmental emission. However, owing to the high cost of the new technologies, the optimal planning of residential microgrids has attracted more attention. An appropriate microgrid with a suitable generation storage system can be designed on the basis of the geographical specifications of the rural area and the availability of the system components in the region.
Diversity of electricity generation technologies, application of renewable energy resources, and advancements in energy storage technologies have granted more flexibility to integrate microgrids in rural areas. Microgrids are a valuable option for residential electrification in rural areas. Mohammad Hassan Khooban, in Residential Microgrids and Rural Electrifications, 2022 Abstract MGs in the network can use a common bus to connect with main grid or a separate electrical connection to connect themselves with the main grid. All MGs in the network can operate in both grid-connected and island mode. Each MG in a network can be formed with dispatchable/nondispatchable DERs, ESSs and controllable/uncontrollable loads. NMGs can be classified into three types based on network formation: star-connected, ring-connected and mesh-connected NMGs. Thus, this chapter discusses the most common types of NMGs used in recent research. In practice, limiting interconnection types amongst MGs is extremely difficult. The interconnection amongst MGs depends on the requirement and agreement amongst MGs in a network during the formation of that network. MGs in a certain geographical area can form a physical network to achieve a local/global objective through cooperative interaction amongst MGs and with the main grid. Hamdan, in Cyberphysical Infrastructures in Power Systems, 2022 2.1.2 Types of networked microgrids In this chapter, we discuss an optimal configuration of monitoring and controlling and the communication of such a system. In the community microgrid, the aggregator should have good visibility of residential loads and DERs to monitor/control this sector's loads. This issue becomes more complex when residential buildings are included in a community microgrid. Thus, microgrids should have monitoring and control capability of loads and distributed energy resources (DERs) located within each building. The community microgrid seems more challenging to the owner/operator, known as the aggregator, who oversees the optimal planning and efficient operation of these microgrids. Microgrids are grouped into a single-owned building or campus as well as a community microgrid that serves various buildings with multiple owners. Microgrids are emerging to eliminate the growth in load, to integrate intermittent renewable energy resources, and to prevent prolonged power outages.
