Abstract


The main objective of the Economic Load Dispatch (ELD) is to determine the power by all committed generating units so that generating cost is minimized, while satisfying the load demand and inequality constraints. This paper represents an algorithm motivated by the ‘law of gravity’ and interaction among the masses to solve ELD problems, called ‘Gravitational Search Algorithm’. This proposed algorithm has been tested on some standard power systems including 40-unit, 110-unit, 140-unit, 160-unit, 320-unit systems using different non-linear effect like valve point loading, multi fuel option etc. This result obtained by using proposed method compared with other methods shown less computational time over other existing algorithm.
