摘　　要：冷热电联供微网是综合能源系统的典型应用,考虑综合需求响应的微网规划是提高微网系统性能的基础。基于冷热电联供微网中气、电、冷、热等不同形式能源间的耦合互补、互替、互动关系,建立微网系统中IDR实施的具体模型-储能设备、可控负荷(可削减负荷、可平移负荷)、可转换负荷的模型和系统能量流,综合考虑年等值投资成本、年燃料费用、年运行管理费用和年IDR成本,建立计及IDR的微网容量优化配置模型,约束条件中计及IDR约束、可靠性约束等,算例中多场景对比结果表明,IDR提高了系统配置的经济性和可靠性,促进可再生能源的消纳,验证了模型的正确性和合理性。Combined cooling,heating and power(CCHP)microgrid is a typical application of integrated energy system,microgrid planning is the basis to improve the performance of microgrid system considering the integrated demand response.Based on the coupling,complementarity,alternation and interaction among different forms of energy such as gas,electricity,cold and heat in the microgrid,the specific models of energy storage equipment,controllable load(reducable load,translatable load),convertible load are established which are the integrated demand response(IDR)implementation in microgrid system,the system energy flow is established,and an optimal allocation model of microgrid capacity considering IDR is established,costs are considered comprehensively,including annual equivalent investment cost,annual fuel cost,annual operation and management cost and annual IDR cost,the IDR constraints and reliability constraints are taken into account in the constraints.The results of multi-scenario comparison in the example show that IDR improves the allocation economy and reliability of system,promotes the consumption of renewable energy,the correctness and rationality of the model are verified.
