Implementation of MRPSO techniques on economic load dispatch problem considering various generator constraints

This article presents moderate-random-search strategy PSO called MRPSO to solve both convex and non-convex economic load dispatch (ELD) problem of the thermal unit. Here transmission loss is not considered. The proposed methodology can take care of ELD problems considering nonlinearities such as valve point loading, ramp rate limits, prohibited zone etc. The objective of economic load dispatch is to determine the optimal power generation of the units to meet the load demand, such that the overall cost of generation is minimized, while satisfying different operational constraints. The effectiveness of the proposed algorithms has been verified on different test systems with equality and inequality constraints. Compared with the other existing techniques demonstrates the superiority of the proposed algorithms.
