Sustainable Commitment Scheduling for Power, Heat, and Natural Gas Dispatch

Abstract

This manuscript presents commitment scheduling of power, heat and natural gas in presence of thermal generating units (TUs), cogeneration units (CUs), heat only units (HUs), solar PV plants, wind turbine generators and PEV parking lot with charging and discharging facility considering carbon capture. Power to gas technology comprising of carbon capture unit, electrolyzer, hydrogen storage unit, and methanation procedure, is used to provide natural gas demand using CO₂ taken from TUs, CUs, HUs and hydrogen produced by electrolyzer. Total operative cost of TUs, CUs, HUs plus running cost of WGs and SPs are minimized whilst fulfilling a number of unit commitment constraints as well as generation scheduling constraints. Binary differential evolution along with priority list is applied for solving this problem. Numerical results of the system are comprehended for giving valued particulars for operative problem.
