Frequency control scheme based on the CDM-PID controller for the hybrid microgrid system with stochastic renewable generators

Automatika, 2023
In this paper, we introduce a Coefficient Diagram Method (CDM) to design a conventional PID controller. This controller is used to decrease the frequency fluctuations of a microgrid system composed of two renewable energy sources (WTG and STPG) and four ...
