- To fulfill the ever-increasing energy demand and to curb the innumerable threats that conventionalenergy generation techniques are posing, we are forced to explore the use of renewableenergy sources. The contribution of renewable energy sources in total primary energy consumptionhas been steadily rising in the past few decades. The increased penetration of the renewableenergy sources into the power system network have provided enormous opportunities and theirown set of challenges to deal with. Hence, the study of various control strategies and theirperformances employed to integrate the renewable energy sources to the existing power systemnetwork is of prime importance. In this research, a novel technique is proposed to analyze theperformance of the close loop system used to integrate a renewable energy source to the powersystem network.A solar photovoltaic array connected to a load interfaced via a dc-dc converter is consideredas the test system in this research. An optimal control theory based linear quadratic regulator(LQR) controller is designed for the closed loop operation of the system. Derivative basedsensitivity functions are formulated to validate the performance of the designed closed loopcontroller. The contribution of closed loop controller to the stability and overall system responseis analyzed using the sensitivity functions. The system characteristics such as settling time andpercent overshoot are modified to meet the desired requirements using the derived sensitivityfunctions. A simplified model of the system is built using MATLAB/Simulink and several casestudies are performed on the test system to validate the claims of this research.
