Electrothermal Economic Dispatch for Wind Power Consumption by Bypass Compensation Heating Under Carbon Trading Mechanism
Aiming at the prominent wind abandonment problem in"Three Norths"areas,an electrothermal economic dispatch scheme is proposed to realize the wind consumption using the CHP steam turbine bypass compensation heating.The dispatch model takes into account the stepped carbon trading mechanism,and two electrothermal decoupling schemes for heat supply compensation,namely,the whole bypass and the HP-LP bypass are considered.The coal consumption calculation model of bypass heating is established based on the heat quality method.Effects of the bypass heating during the peak period of wind power generation at night on coal consumption and wind curtailment are studied,and the electrothermal operation characteristics of thermal power units are analyzed.The calculation example results show that the dispatch scheme of the whole bypass heating can effectively achieve the electrothermal decoupling,which brings the best low-carbon economic electrothermal distribution results,and the CHP steam turbine has good electrothermal operation characteristics.
