This paper presents a novel approach to solve the security constrained unit commitment problem using decomposition technique. The method applies an improved integer coded genetic algorithm (ICGA) to schedule the commitment states of units. ICGA technique reduces the size of chromosomes and computation time significantly. Here, the proposed ICGA has been enhanced by using perturbation operator. Simulation...
Summary form only given. This study concentrates on the strategic interaction among suppliers in a centralized market where electrical energy and spinning reserve are simultaneously traded. A bilevel optimization technique and a mathematical program with equilibrium constraints approach are utilized to develop optimal bidding strategy for competitive suppliers participating in these markets.The strategic...
In this paper, we present the status of electricity deregulation in the United States. Furthermore, we describe the use and advantages and disadvantages of locational marginal pricing (LMP) in deregulated power markets. Finally, we present the use of LMP in analyzing electricity pricing in a deregulated electric utility environment. Using LMP, our proposed methodology for determining electricity prices...
In this paper, a systematic risk-based transmission line expansion approach is studied. The approach addresses three objectives: load-driven expansion, security-enhancement expansion and risk-based expansion. The first problem identifies transmission expansions necessary to correct inadequacy; the second problem identifies transmission expansion necessary to correct insecurity; the third problem balances...
