摘　　要：电、气、冷、热等多种能源耦合的园区综合能源系统(IES)有助于提升对可再生能源发电的消纳,提高能源利用效率。文中提出基于分布鲁棒优化的园区IES日前低碳经济调度策略。首先,构建考虑碳交易和综合需求响应的园区IES的运行架构,并建立碳交易模型和基于用户用能习惯的综合需求响应模型。其次,以最小化运行成本为目标,并考虑园区IES运行约束和燃料掺氢的电转气(P2G)设备两阶段运行等约束,建立了园区IES日前低碳经济调度模型。然后,构建计及用户响应不确定性的园区IES分布鲁棒低碳经济调度模型,并利用对偶原理将该分布鲁棒优化模型转化为二阶锥优化模型,采用商业求解器CPLEX求解。最后,以包含电、气、冷、热多种能源耦合的典型园区IES为例,对所提优化模型的可行性和有效性进行了验证。算例结果表明,采用所提出的低碳经济调度策略可以有效提升园区IES运行的经济性和消纳可再生能源发电的能力,降低IES碳排放和运行风险。The park-level integrated energy system(IES) with multi-energy complementation of electricity,gas,cooling and heat could promote the accommodation of power generation of renewable energy and improve the energy utilization efficiency.A dayahead low-carbon economic dispatch strategy for the park-level IES based on distributionally robust optimization is proposed.First,the operational framework of the park-level IES considering the carbon trading and integrated demand response(IDR) is introduced,and a carbon trading model and an IDR model based on customer energy consumption behaviors are proposed.Secondly,with the objective of minimizing operation costs and considering the constraints of park-level IES operation and twostage operation of power to gas(P2G) devices with hydrogen doping in the fuel,a day-ahead low-carbon economic dispatch model for the park-level IES is established.Then,a distributionally robust low-carbon economic dispatch model of park-level IES is built with consideration of the uncertainty of customer response.By using the duality theory,the proposed distributionally robust optimization(DRO) model is reformulated as a second-order cone optimization model and solved by the commercial solver CPLEX.Finally,by taking a typical park-level IES with multi-energy complementation of electricity,gas,cooling and heat as an example,the feasibility and effectiveness of the proposed optimization model are verified.The simulation results show that the proposed low-carbon economic dispatch strategy can effectively improve the economy of the park-level IES operation and the renewable energy accommodation ability,and reduce the carbon emission and operation risk of the IES.
