| 中文摘要:分析了MG中分布式电源的功率特性和需求侧响应的基本理论与相关政策，并建立了DG的数学模型和基于负荷分类的DR模型；综合考虑微源的出力成本、需求侧管理成本和环境治理费用，建立了考虑需求侧管理的多目标微电网优化调度模型，引入不同的孤岛微电网运行评价指标评价DR对微电网经济性、环保性以及可靠性的影响，并选择不同的场景分析验证。采用改进粒子群算法优化外点法对规划问题进行求解，在将约束条件纳入目标函数的同时，尽可能避免求解规划时陷入局部极值的问题。算例分析表明，通过考虑需求侧管理，可以增加可再生能源的消纳，减轻负荷高峰时段的供电压力，缓解孤岛系统供电不足的问题，并有效提高微电网的整体效益。 |

| Abstract:Firstly， this paper analyzes the power characteristics of the distributed generation （DG） and basic theories and related policies of demand response （DR）， and establishes the mathematical model of DG and the DR model based on load classification. Secondly， with comprehensive consideration of the output cost of micro power generation， DR management cost and environment treatment cost， a multi-objective microgrid optimization scheduling model is established considering the demand side management， and different islanded microgrid operation evaluation indexes are introduced to evaluate the impact of DR on the economy， environmental protection and reliability， and different scenarios are selected for analysis and verification.The improved particle swarm optimization-exterior point method （IPSO-EPM） is used to solve the planning problem. While the constraints condition is included in the objective function， the problem of falling into the local extremum during the planning is avoided as much as possible. The analysis of the example shows that the proposed model can increase the consumption of renewable energy， reduce the power supply pressure during peak load hours， alleviate insufficient power supply， and effectively improve the overall efficiency of the microgrid by taking DR into consideration. |
