计及电网辅助服务收益的区域供能站热泵扩展规划方法

Expansion Planning Method of Heat Pump for Regional Energy Stations Considering the Benefits of Grid Ancillary Services

针对双碳目标下区域能源系统的减排需求,提出了一种考虑电网辅助服务收益的区域能源站热泵扩展规划方法,支撑将热泵等低碳供能技术集成到现有区域能源系统的设备选型。首先,构造了考虑外部电网调控需求的区域供能站多能耦合模型。在此基础上,提出了计及电网辅助服务收益的双层扩展规划模型,综合考虑能源成本、辅助服务价格、既有储能容量、碳排成本等因素对于规划结果的影响。最后,以某大学校园供能站热泵替代热电联产机组为例,比较分析了上述因素对区域供能站扩展规划结果的影响,验证了所提方法的有效性。

To address the need of carbon emission peak and carbon neutrality target on local energy systems,an optimal expansion planning method of heat pump was proposed for regional energy stations considering the benefits from ancillary services.The method was used to support the integration of new technologies such as heat pumps into existing local energy systems.Firstly,an integrated power,gas and heating system model was developed to reflect the interactions between different energy systems.On this basis,a bi-level expansion planning model that considers the benefits of grid ancillary services was proposed,taking into account the impact of factors such as energy cost,ancillary services price,existing energy storage capacity,and carbon emission cost on the planning results.Finally,a university campus energy supply station where heat pump replaces combined heat and power units was used as an example to analyze the effects of the above factors on the expansion planning results,validating the effectiveness of the proposed method.
