Abstract

In this paper, an efficient meta-heuristic satin bowerbird optimization (SBO) algorithm is presented for congestion management (CM) in the deregulated power system. The main objective of CM is to relieve congestion in the transmission lines using a generation rescheduling-based approach, while satisfying all the constraints with minimum congestion cost. The SBO is a nature-inspired algorithm, developed based on the ‘male-attracts-the-female for breeding’ principle of the specialized stick structure mechanism of satin birds. The proposed approach is effectively tested on small and large test systems, namely, modified IEEE 30-bus, modified IEEE 57-bus, and IEEE 118-bus test systems. The constraints like line loading, line limits, generator limits, and bus voltage impact, etc., are incorporated into this study. The proposed technique gives superior results with regards to congestion cost and losses compared with various recent optimization algorithms.

Summary

Introduction

The electric power industry is switching over from being vertically integrated into being a deregulated utility. The vertical utility system has common control over all the transmissions, distributions, and generations in the power system. In a deregulated utility system, the transmission, distribution, and generation systems work independently of the environment and, it becomes a challenge for independent system operators (ISOs) to manage [1]. Congestion occurs in the transmission network due to natural hazards, transmission line failure due to miss-operation, and all the market participants purchasing the power from the cheapest sources of the area at the same time. To manage the operation of transmission systems in a deregulated power system based on optimal power flow (OPF), price–area congestion control and a transaction-based model CM problem have been analyzed in depth [4]. Satin bowerbirds live in the rainforest and mesic forest in Australia They are closely related to the other bowerbirds. Male satin bowerbirds construct specialized stick structures called bowers, where male bowerbirds attract the female by dancing and by making a noble bower and decking the surrounding area
