摘要
未来,风电将和火电享有同样的出力水平,同时承担一定的系统调节任务,大型风电场亟需寻求一种新的途径来提升消纳水平。能源互联网的推进和售电侧的开放为综合能源服务商(integrated energy service provider,IESP)聚合多类型供能设备和综合柔性负荷直接满足风电的消纳需求提供了环境和契机。据此,在分析我国目前风电的运营现状的基础上,讨论了可调度风电场的消纳需求,考虑IESP自有供能设备的发电/热响应能力和辖区综合需求响应电热负荷的可控性、采暖负荷的弹性,提出了一种基于风电消纳需求的风电场-IESP协同运营模式(windfarm-IESP,WICOM),构建了IESP的综合响应模型,进一步以IESP收益最大为目标,建立了源荷电热日前经济调度模型,并以算例证明WICOM在提升IESP收益和风电消纳水平上所起的积极作用。
In the future, wind power will enjoy the same output level as thermal power and undertake certain system regulation tasks at the same time. Large-scale wind farms urgently need to find a new way to improve their accommodation levels. Promotion of energy internet and opening of power-sale-side provide an environment and opportunity for integrated energy service provider (IESP) to aggregate multiple types of energy-supplied equipment and comprehensive flexible loads to directly meet the demand for wind power accommodation. Based on analysis of current status of wind power operation in China, this paper discusses the accommodation demand of schedulable wind farms. A wind farm-IESP cooperative operation mode (WICOM) based on wind power accommodation demand is proposed considering the response capability of self-operated equipment of IESP, controllability of integrated demand response load and elasticity of heating load in jurisdictions. Then a comprehensive response model of the IESP is constructed, and a day-ahead economic dispatch model is established with the goal of maximizing IESP’s revenue. Finally, simulation validates the positive role of WICOM in improving income of IESP and accommodation level of wind power.
