With increasing concern of environmental protection, renewable energy sources especially wind power are widely applied as a mean to reach emission reduction. Although wind generation does not produce harmful emissions, its effect on the generation dispatch of conventional plants can actually cause an increase of emission especially during low and middle power demand period. A multi-objective generation...
This paper describes secant method combined with particle swarm optimization for solving economic dispatch (ED) problem with prohibited operating zones. Two stages are involved in the proposed approach to solve the ED problem with prohibited operating zones. First, the range of output powers near to the global optimal solution is determined by secant method without considering prohibited zones and...
This paper presents a new approach with muller method for solving profit based unit commitment (PBUC). In Deregulated environment, the generation companies (GENCOs) schedule their generators to maximize their profit rather than satisfying the power demand. The PBUC problem is solved by the proposed approach in two stages. Initially, the information of committed units is obtained by a simple approach...
This paper presents a new approach with Muller method for solving profit based unit commitment (PBUC). In deregulated environment, the generation companies (GENCOs) schedule their generators to maximize their profit rather than satisfying the power demand. While solving the PBUC problem, the information of forecasted price at the given predicted power demand is known. The PBUC problem is solved by...
This paper describes the application of secant method for solving economic dispatch (ED) problem with generator constraints and transmission losses. The proposed algorithm involves the selection of minimum and maximum incremental fuel costs (lambda values) and then the evaluation of optimal lambda is done by root finding techniques at required power demand. The proposed algorithm has been tested on...
