Distributed Active Power Control

Abstract

This chapter discusses three distributed control methods/solutions for active power control, where the applications of these solutions differ depending on the control targets, control objectives, and available resources. The first control solution introduced is subgradient‐based active power sharing, which aims at maintaining the supply‐demand balance in a microgrid. The second control method is used for the economic dispatch (ED) of the smart grids, which is not limited to the microgrid. The last control solution aims at integrating the ED with the frequency control. Focusing on the self‐contained, medium voltage, and small‐scale microgrid, which consists of multiple renewable energy sources, the chapter aims to maintain the supply‐demand balance of active and reactive power and regulate the voltage magnitude and system frequency to the desired values. A multi‐agent system‐based fully distributed control approach for renewable generators’ controller consisting of two control levels is proposed.
