Abstract

Transmission congestion is a vital problem in the power system security and reliability sector. To ensure the stable operation of the system, a congestion free power network is desirable. In this paper, a new Congestion Management (CM) technique, the Wind integrated Compressed Air Energy Storage (WCAES) system is used to alleviate transmission congestion and to minimize congestion mitigation cost. The CM problem has been solved by using the Generator Sensitivity Factor (GSF) and the Bus Sensitivity Factor (BSF). BSF is used for finding the optimal location of WCAES in the system. GSF with a Moth Flame Optimization (MFO) algorithm is used for rescheduling the generators to alleviate congestion and to minimize congestion cost by improving security margin. The impact of the WCAES system is tested with a 39 bus system. To validate this approach, the same problem has been solved with a Particle Swarm Optimization (PSO) algorithm and the obtained results are compared with the ones from the MFO algorithm.

Summary

Introduction

Especially in a deregulated environment, is one of the most important issues for system operators. Within fixed thermal limits of transmission lines, thermal generators are rescheduled for congestion alleviation [1]. In [2,3,4], congestion mitigation techniques are discussed with the integration of Flexible AC Transmission System (FACTS) devices. The generator rescheduling approach is one of the most important techniques in CM problem. Active power rescheduling is done for congestion mitigation by using the relative electrical distance (RED) approach [5]. Reactive power is important for congestion mitigation. Market flow strategy concepts are often used for congestion management [7,8,9]
