Load Frequency Control of Solar PV and Solar Thermal Integrated Micro grid using Narma-L2 Controller

Abstract

In this paper a novel approach to load frequency control of a microgrid with integrated Solar PV and Solar thermal generator is presented. A nonlinear adaptive controller based on an autoregressive moving average algorithm (NARMA) is used to control the frequency of the system. The objective of such a controller is to regulate and minimize frequency deviation due load changes. Further, a novel metaheuristic approach called Modified Whale Optimization Algorithm (MWOA) is used for creating an optimal PID controller to be used for frequency control. Finally, a comparative study between the proposed NARMA-L2 controller, WOA tuned PID controller and conventional PID controller is presented. From a series of experiments, it is concluded that the proposed NARMA-L2 controller outperforms other techniques of frequency control and gives the best result in terms of overshoot and settling time.
