Optimal Operation of a Residential Energy Hub in the Presence of an Electric Vehicle using Whale Optimization Algorithm

Abstract

An energy hub is a unit that receives various energy carriers such as electricity and natural gas at its input and, after converting or storing energy, offers different energies at its output such as electricity, heating, and cooling. One of the most cost-effective solutions for utilizing the electricity and gas industry infrastructure is to consider both of them as an integrated system, such as an energy hub in the planning and operation of energy systems. This paper studied the home energy hub model, including a combined heat and power (CHP) system and a grid-connected electric vehicle (PHEV). The operation of the energy hub is considered a linear optimization problem mixed with integers (MILP); Therefore, the goal is to minimize the co-payment cost of a residential house that uses the WOA optimization algorithm. Solving this optimization problem includes the amount of energy carriers entering the hub, the energy converted to CHP, and the charge and discharge of PHEV.
