Design and analysis of mrpid tuned Alo optimized abt of automatic Generation control for dg Penetrated power system

Abstract

Many power systems are interconnected to meet the load demand and increase the power system reliability. Power systems are interconnected for the economy and continuity of power supply. Load disturbance due to the occurrence of consistent and frequent change in loads result in tie-line power flows from the interconnected areas and the frequency of the system variations and thus, the system becomes unstable. So, it necessitates Automatic Generation Control (AGC) to keep up the stability of the load deviations. newlineAlong with the AGC in order to force the network discipline and to manage the wide changes in the frequency Accessibility Based Tariff (ABT) has been executed in regional grids. The ABT Mechanism is the largest revolutionary Regulatory Reform that has taken place in Indian Electrical Grid decentralisation. In this research, AGC with ABT is analysed for hydrothermal -Photovoltaic (PV)-wind interconnected power system. newlineTo enhance the performance of AGC, wavelet-based Multi-Resolution Proportional Integral and Derivative (MRPID)controller for AGC in an interconnected power system. In this analysis, the Ant-lion optimisation (ALO) algorithm is proposed with MRPID to control ABT with AGC of the proposed three-area system. ALO is proposed to solve real problems with unknown search spaces and its high capability of avoidance in local optima. newlinePerformance of proposed ALO with MRPID is analysed under various load conditions to minimise generation cost and marginal cost newline
