Economic dispatch of energy sources with restrictions on fuel using TLBO algorithm

ABSTRACTEconomic dispatch aims to make the minimal operating cost of power plant by determining the optimal power produced by each generating unit under constrained circumstances. At the present time, power utilities have stumble upon a fresh dispatch problem, because of crucial concern over fuel shortages. Fuel suppliers increase constraints in their fuel supply contracts that force the utilities to schedule the generation on the basis of fuel availability. With the ever increasing proportion of the fuel budget in the total operating costs, the fuel restricted economic dispatch problem has popped up. A new methodology based on a teaching learning-based optimization algorithm is proposed for solving fuel restricted economic dispatch problems. The potential of the proposed method is tested with standard test systems which include different cost characteristics. The obtained results are compared to other algorithms surfaced in the recent state-of-the-art literature, confirming the effectiveness of the devel...
