考虑供需双边响应的综合能源系统优化调度OA北大核心CSTPCD

To explore flexible resources on both the supply and demand sides of integrated energy systems(IES)and optimize their low-carbon and economic performance,this paper proposes an optimal scheduling strategy for IES that considers the bilateral response of supply and demand.First,to enhance the flexibility of IES energy supply,an electric boiler and an organic Rankine cycle power generation device were introduced.A supply-side response model was developed to accommodate the flexible output of electric and thermal energy from a combined heat and power(CHP)unit.A flexibility indicator—the ratio of electric to thermal energy output—was proposed to measure the operational flexibility of the CHP unit.Second,based on the response characteristics of multiple loads(electricity,heat,and cold),a demand-side response model was constructed,incorporating orderly charging and discharging strategies for electric vehicles to explore the schedulable potential of the demand side.Finally,an IES supply-demand collaborative optimization model was established,aiming to minimize the sum of energy purchase costs,wind abandonment costs,response compensation costs,operation and maintenance costs,and carbon trading costs.The results demonstrate that the proposed strategy effectively utilizes the coordination and complementarity of flexible resources between supply and demand,enhancing the low-carbon performance,economic efficiency,and flexibility of IES operation while promoting the grid-connected consumption of wind power.
