Congestion Management in Deregulated Power System: A Review

Abstract

Restructuring has swept through all potential fields in recent decades, including the electric supply industry. Restructuring has resulted in significant changes, such as the fact that power is now a commodity and has become deregulated. In such a competitive industry, there are a plethora of participants. Overloading transmission networks or network congestion have come from the emergence of deregulated electricity systems. Congestion has significant consequences for electricity systems, including system failure. When transmission networks fail to transfer power in accordance with load demand, congestion occurs. Congestion management methods, which play a major part in today’s deregulated electricity systems, are used to address these issues. Furthermore, the open access transmission network has aggravated the issue of congestion. As a result, power system congestion management is critical to the power sector. The relevance of each proposed method or technique in relieving congestion and minimizing system operating expenses is reviewed in this paper using the work of various publications.
