| 摘要: |
| 广域民用负荷参与需求响应目前已成为促进风电消纳的新途径，然而广域民用负荷的调节时序特性复杂，使其在电网层的优化调度中难以对广域民用负荷进行直接调度。为此，提出了一种基于代理技术的广域源-荷双层递阶协同优化调度模型。在负荷代理分区聚合广域民用负荷的基础上，上层(电网调度层)模型基于负荷代理内聚合负荷的简化调节能力，考虑负荷调节时序的不确定性，协同优化风电、常规电源和负荷代理的初始调度计划；下层(负荷代理层)模型考虑民用负荷个体的调节性能约束，以与负荷代理的初始调度计划偏差最小为目标，优化得到民用负荷个体的调度计划；在上、下层模型之间引入递阶协同优化环节，将下层模型的优化解反馈传递给上层模型，以修正风电场、常规电源的初始调度计划，形成最终广域源-荷调度方案。算例仿真结果验证了所提模型的有效性和优越性，表明所提模型能在保证优化效果的同时显著提升求解效率，为广域民用负荷直接参与电网优化调度提供一种切实可行的解决思路。 |

| Abstract: |
| Participation of wide area civil loads in demand response has become a new way to promote wind power consumption. However, the complex regulation time sequence characteristics of wide area civil loads make it difficult to conduct direct scheduling of wide area civil loads in the optimal scheduling of power grid layer. Therefore, a double-layer hierarchical and cooperative optimal scheduling model of wide area source-load based on agent technology is proposed. On the basis of load agent partition aggregating wide area civil loads, the upper layer(power grid scheduling layer) model cooperatively optimizes the initial scheduling plans of wind power, conventional power generation and load agent based on the simplified adjustment ability of aggregated loads within the load agent, considering the uncertainty of load regulation time sequence. Considering the regulation performance constraints of civil load individuals, the lower layer(load agent layer) model optimizes the scheduling plan of civil load individuals with the objective of minimizing the deviation from the initial scheduling plan of load agents. A hierarchical and cooperative opti-mization link is introduced between the upper and lower layer models to transmit the optimization solution of lower layer model to upper layer model, which modifies the initial scheduling plans of wind farms and conventional power generations and forms the final wide area source-load scheduling plans. Simulative results of examples verify the effectiveness and superiority of the proposed model, and show that the proposed model can not only ensure the optimization effect, but also significantly improve the solution efficiency, thus providing a feasible solution for wide area civil loads to directly participate in the power grid optimization scheduling. |
