- Abstract
Summary: In general, the load demand of a standard microgrid system, changes on an hourly basis. Keeping in line with the rise and fall of this load demand curve, utilities fix different prices at different hours, which is termed as time of usage‐based electricity pricing. Elastic and inelastic are the two types of load that comprise the hourly demand of the microgrid system. Demand‐side management (DSM) shifts the elastic loads from peak load hours to those hours when the utility charges less thereby, restructuring the entire demand model‐based on demand‐price elasticity. Considering that the elastic loads contribute about 5% to 20% of the total load consumed during an hour, this paper implements a novel hybrid CSAJAYA algorithm to minimize the overall cost of a microgrid system considering DSM strategy. The various cost components taken into consideration are fuel cost, penalized emission cost, the cost of operation and maintenance, the cost of depreciation, etc. Numerical results depict that 30% to 40% decrement in overall generation cost was realized when DSM‐based energy management microgrid system was performed using the novel hybrid algorithm when compared to those available in the literature. Measures of central tendencies analysis claim the superiority of the proposed optimization algorithm.
