Depending upon the mode of operation, an autonomous microgrid is connected to AC loads through AC bus. A microgrid operating in grid-tied mode is connected to main grid through AC bus where local AC loads are also connected . Fig. 2.2 presents the schematic diagram of AC microgrid structure. Figure 2.2. AC microgrid structure.
The layered structure of the microgrid is explained followed by brief explanation of modes of operation, control, and hierarchical control scheme of the each microgrid. The concept and modeling of PV, MPPT algorithms, wind turbine system, batteries, and FC is also discussed.
3.1. AC microgrid In AC microgrid structure, an AC bus is created, and all microsources with variable frequency and variable voltage AC output are connected to AC bus through AC/AC power electronics converter. Sources with DC output are connected to AC bus through DC/AC converter.
The nature of microgrid is random and intermittent compared to regular grid. Different microgrid structures with their comparative analyses are illustrated here. Different control schemes, basic control schemes like the centralized, decentralized, and distributed control, and multilevel control schemes like the hierarchal control are discussed.
The microgrid control consists of: (a) micro source and load controllers, (b) microgrid system central controller, and (c) distribution management system. The function of microgrid control is of three sections: (a) the upstream network interface, (b) microgrid control, and (c) protection, local control.
The two predominant modes of operation of the microgrid, that is, islanded mode and grid-connected mode, are also discussed in the following chapter. The chapter also deals with different forms of RES, modeling of various components of microgrid, and applications associated with microgrid. 1.1. Introduction
