Based on these factors, control structures can be classified and briefly explained as follows [9]:Centralized: There is only a single central controller managing, communicating, and controlling the whole MG/system.Distributed: There are several individual controllers, and some information about their behavior is shared among them.Decentralized: Several individual controllers exist; however, no information is shared among them. [pdf]
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.
Books > Microgrids: Dynamic Modeling,... > Microgrid Control: Concepts and Fundame... The control system must regulate the system outputs, e.g. frequency and voltage, distribute the load among Microgrid (MG) units, and optimize operating costs while ensuring smooth transitions between operating modes.
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.
Networked controlled microgrid . This strategy is proposed for power electronically based MG׳s. The primary and secondary controls are implemented in DG unit. The primary control which is generally droop control is already discussed in Section 7. The secondary control has frequency, voltage and reactive power controls in a distributed manner.
A microgrid (MG) is a building block of future smart grid, it can be defined as a network of low voltage power generating units, storage devices and loads. System of systems (SoS) is another concept involving large scale integration of various systems.
The microgrid control objectives consist of: (a) independent active and reactive power control, (b) correction of voltage sag and system imbalances, and (c) fulfilling the grid's load dynamics requirements. In assuring proper operation, power systems require proper control strategies.

Recently direct current (DC) microgrids have drawn more consideration because of the expanding use of direct current (DC) energy sources, energy storages, and loads in power systems. Design and analysis of a standalone solar photovoltaic (PV) system with DC microgrid has been proposed to supply power for both DC and alternating current (AC) loads.
The research further seeks to formulate and design an optimum, robust, sustainable and economical solar PV based microgrid solution for electrification of a remote area focusing on green areas that currently have no access to electricity. The objective is to achieve a system that is cost effective, reliable and sustainable.
In order to overcome the problems associated with the intermittency of solar PV and enhance the reliability, energy storage systems like batteries and/or backup systems like diesel generators are commonly included in the microgrids [11, 12].
Technical assessment is based on the nature of the energy sources and the load of the microgrid. For a solar PV-based microgrid, the main technical aspects that are necessary to be considered include rating of PV modules, tilt angle, fill factor, MPPT, PV efficiency, and efficiencies of the power electronic converters.
Microgrid design consists of several aspects of the microgrid such as generation modelling, load modelling, storage, local network, sizing of the components and determination of the control strategy. Sizing of the system components is a very important step in the design of PV microgrid systems.
The increasing demand for reliable and clean energy promotes the installation of PV-based microgrids. Appropriate sizing of microgrid components, that is, number and size of PV modules, batteries, DGs and associated power electronic devices determines the efficient and economic design of the microgrid.
