Effect of Photovoltaic based Power Generation in Automatic Generation Control of the Interconnected Power System

Abstract

The most important part of the power system is to stabilize the frequency and load. In this paper, automatic generation control (AGC) with additional photovoltaic (PV) system is interconnected with system. To regulate the power system and balance the frequency, Proportional-integral (PI), integral (I) and Proportional-integral-derivative (PID) controllers are connected to each area. This makes it easier to keep the frequency near to its nominal value. Here, the dynamics of the system are evaluated using step load perturbation and random load perturbation in area. The frequency control study is performed using MATLAB Simulink software. The performance of the controller's effectiveness is investigated using performance such as settling time, over shoot and variation in frequency. Based on the simulation study, it is observed that PID controller has better response than the PI controller. As PID controller has fast settling time and steady state error is less compared to PID controller.
