6 FAQs about [Basic principles of photovoltaic microgrid control]

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.

What is the nature of microgrid?

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.

What is a microgrid control system?

Without the inertia associated with electrical machines, a power system frequency can change instantaneously, thus tripping off power sources and loads and causing a blackout. Microgrid control systems (MGCSs) are used to address these fundamental problems. The primary role of an MGCS is to improve grid resiliency.

What are microgrid control objectives?

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.

What is model predictive control in microgrids?

A comprehensive review of model predictive control (MPC) in microgrids, including both converter-level and grid-level control strategies applied to three layers of microgrid hierarchical architecture. Illustrating MPC is at the beginning of the application to microgrids and it emerges as a competitive alternative to conventional methods.

Why is the microgrid concept attractive?

From a grid perspective, the microgrid concept is attractive because it recognizes the reality that the nation’s distribution system is extensive, old, and will change only very slowly. The microgrid concept enables high penetration of DG without requiring re-design or re-engineering of the distribution system itself.
