The difference between microgrid protection and control

The former primarily addresses fault analysis and power system relaying, while the latter delves into dynamical system analysis and feedback control design for a range of objectives (e.g., command .

advance microgrid protection systems and maximize system resilience, reliability, efficiency and minimize grid modernization cost. The motivation for this report is to identify the challenges and technological advancements needed by microgrids in the coming 5-10 years, and how microgrids can achieve: (1) higher resiliency for electric.

The chapter first introduces what a protection system is in general and what the main requirements for the protection of microgrids are. The differences between the protection of microgrids and a conventional distribution network are also elaborated.

The two control approaches for microgrids namely hierarchical control and distributed control are presented in Reference 207, where, the main features of these two methods are discussed and recommendations on how to choose appropriate control for different types of microgrids are made.

Differential protection is a unit/pilot scheme that works whenever the difference between two or more comparable electrical values surpasses a certain threshold. Figure 16 depicts a current-differential protection scheme in which system currents at both ends of the protected line are measured and then compared through the differential relay to .

6 FAQs about [The difference between microgrid protection and control]

Can a microgrid protect a power system?

Protection systems need to be reviewed to consider the integration of distributed generation technologies. The presence of a microgrid causes many challenges in the protection of the power system. This study addressed these challenges and their solutions.

Are microgrids a threat to protection systems?

While microgrids have many benefits for power systems, they cause many challenges, especially in protection systems. This paper presents a comprehensive review of protection systems with the penetration of microgrids in the distribution network.

Is microgrid protection based on communication?

Most studies on microgrid protection in islanded mode were communication-based. Wide-area protection based on measurements obtained from PMU and intelligent protection systems can resolve many issues related to the protection and control of the smart grids in the future.

What is the framework of microgrid protection system?

The framework of microgrid protection system should be meticulous, reliable and must have high speed and low-cost operation. The process of microgrid protection must have following steps as shown in Fig. 4, which need to be followed starting from the occurrence of fault to the restoration of the normal operation of the system. Fig. 4.

What are the components of microgrid control?

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.

How does a microgrid protection system change with the topological changes?

The protection system adaptively changes with the topological variations of the power system. References [42, 44] proposed the protection of a microgrid with a communication network using digital relays. These methods use differential protection for low fault currents, such as in an HIF and inverter-based-microgrid.
