Locating series FACTS devices for congestion management in deregulated electricity markets

One of the most important tasks of System Operator (SO) is to manage congestion as it threatens system security and may cause rise in electricity price resulting in market inefficiency. In corrective action congestion management schemes, it is crucial for SO to select the most sensitive generators to re-schedule their real and reactive powers and the loads to curtail in extreme congestion management. This paper proposed the selection of most sensitive generators and loads to re-schedule their generation and load curtailment based on the improved line flow sensitivity indices to manage congestion. The impact of slack bus on power flow sensitivity factors has been determined to encourage fair competition in the electricity markets. Effect of bilateral and multilateral transactions, and impact of multi-line congestion on congestion cost has also been studied. The generators reactive power bid has been modeled by a continuous differentiable tangent hyperbolic function. The proposed concept of congestion management has been tested on a practical 75-bus Indian system and IEEE-118-bus test system.

Shaun McRae of the University of Michigan reviews “The Economics of Electricity Markets: Theory and Policy”, by Pippo Ranci and Guido Cervigni. The Econlit abstract of this book begins: “Six papers address the main issues that arise when competition is introduced into the electricity industry. Papers discuss wholesale electricity markets (Guido Cervigni and Dmitri Perekhodtsev); generation capacity adequacy (Cervigni, Andrea Commisso, and Perekhodtsev); congestion management and transmission rights (Perekhodtsev and Cervigni); competition policy in the electricity industry (Cervigni and Perekhodtsev); retail competition (Anna Creti and Clara Poletti); and climate change and the future of the liberalized electricity markets (Cervigni). Ranci is Professor of Economic Policy at the Catholic University of Milan and Chair of the Board of Appeal of the European Agency for the Cooperation of Energy Regulators. Cervigni is Research Director at the Center for Research on Energy and Environmental Economics and Policy at Bocconi University and Chief Economist at A2A S.p.A. Index.”
