摘　　要：为进一步促进园区级综合能源系统(park integrated energy system, PIES)的可再生能源消纳和碳减排,优化园区级综合能源系统的运行总成本,提出一种碳-绿色证书交易机制下考虑回收电转气(power to gas, P2G)余热和需求响应的园区级综合能源系统优化调度模型。首先,考虑阶梯式碳交易机制和绿色证书交易制度,以促进可再生能源的消纳和碳减排。其次,引入回收余热的电转气设备,优化电-热-气耦合关系来提高系统消纳可再生能源和碳减排水平。然后,建立含可削减、转移、替代负荷的需求侧响应模型,指导用户的用能方式由高能耗、高污染向低碳、可持续转变。最后,以购能成本、弃风惩罚成本、需求响应补偿成本、阶梯式碳交易成本、绿色证书交易收益之和最小为目标,构建PIES优化调度模型。算例结果表明,该模型可以有效促进可再生能源消纳和碳减排并降低系统运行成本。In order to further promote the renewable energy consumption and carbon emission reduction of the park integrated energy system(PIES), and optimize the total operation cost of the PIES, this paper proposes a PIES optimization scheduling model considering the recovery of waste heat from power to gas(P2G) and demand response under the carbon-green certificate trading mechanism. Firstly, the stepwise carbon trading mechanism and green certificate trading system are considered to promote the consumption of renewable energy and carbon emission reduction. Secondly, the P2G equipment to recover waste heat is introduced, and the electric-heat-gas coupling relationship is optimized to improve the system’s renewable energy consumption and carbon emission reduction level. Then, a demand-side response model including reduced, transferred and substituted loads is established to guide users to change their energy use mode from high energy consumption and high pollution to low-carbon and sustainable. Finally, the PIES optimization scheduling model is constructed to minimize the sum of energy purchase cost, wind curtailment penalty cost, demand response compensation cost, stepped carbon trading cost and green certificate trading revenue. The simulation results show that the model can effectively promote the renewable energy consumption and carbon emission reduction and reduce the system operation cost.
