Optimal operation of the multi-carrier energy system with smart scheduling of consumption

Abstract

The global energy issue and lack of fossil fuels are obviously difficult concerns, prompting experts to look for other solutions. In this paper, the day-ahead operation of the multi-carrier energy system (MCE) to minimize operational costs, emission polluting and maximizing consumers’ comfort is presented. The optimal energy scheduling of consumption by energy demand curtailment strategy (EDCS) in the peak demand of electrical energy is proposed. Also, the operation of the energy storage via an onsite generation strategy (OGS) for consumers is considered by energy storage systems. The EDCS and OGS are modelled based on Demandside Management (DSM). The fuzzy method is taken into account as an optimization approach and objective functions. Finally, two scenarios using numerical simulation are studied to demonstrate the effectiveness of the approach for energy optimization in MCE. The results of the scenarios are studied based on non-participation and participation of the consumers in the scenarios A and B, respectively. The objective functions such as operation costs and emission polluting in scenario B are minimized by 1.63% and 5.35% than scenario A.
