Rescheduling of real power for congestion management with integration of pumped storage hydro unit using firefly algorithm

Abstract—Abstract Post-deregulation era of power system operation produces more pressure on Independent System Operator (ISO) to ensure congestion free transmission network without destroying system security. Inorder to relieve transmission congestion, ISO initiates correct methods by maintaining system reliability
and security. This paper considers a novel efficient technique for congestion management like generator
real power rescheduling by integrating a pumped storage hydro unit (PSHU) in the system. This paper
presents an optimization model for congestion management by incorporating the calculation of two factors
like generator sensitivity factor (GSF) and bus sensitivity factor (BSF). Optimal location of PSHU is
identified using the value of BSF’s and the numbers of participated generators for congestion management
by rescheduling their outputs are determined using the value of GSF’s. The impact of PSHU has been
investigated to manage transmission congestion which further reduces the congestion cost and improves
security of the system. The proposed method for congestion management considering PSHU is tested on
modified IEEE-39 bus New England test system and the validity is obtained by considering the same
problem without the presence of PSHU. The result of proposed work with proper utilization of PSHU illustrates
the impact of PSHU towards the congestion management and also exploration of firefly algorithm
for minimizing the transmission congestion cost.< final year projects >
