摘　　要：高效和清洁的能源利用模式是减少温室气体排放和提高能源网络效率的现实而经济的解决方案。最近越来越多的项目开始关注分布式能源资源,包括光伏(PV)板、热电联产(CHP)、燃料电池及储能系统,因为它们能够作为本地资源利用,以减少因长距离传输而造成的电力损失。提出了一种来评估负荷处的住宅分布式能源(DERs)系统,如CHP,PV系统和热/电储能系统的运行和经济性分析的数学模型,同时考虑能源和辅助服务市场。以此推动分布式能源的财务和弹性价值,并确定关键因素,如分布式能源组合以及电力和天然气配送公司的定价结构。最终得出结论,不同类型的能源电价将影响分布式能源项目的财务方面的问题。此外,研究结果还强调了储能系统激励计划在提高停电期间电网弹性方面的关键作用。Efficient and clean energy using model is a realistic and economical solution for reducing greenhouse gas emissions and improving the efficiency of energy networks.Recently,more and more projects focus on distributed energy resources,including photovoltaic(PV)panels,combined heat and power(CHP),fuel cells,and energy storage systems,as they can be utilized as local resources to reduce power losses due to long-distance transmission.A mathematical model was proposed to evaluate the operation and economic analysis of residential distributed energy resources(DERs)system at load,such as CHP,PV systems and thermal/electric energy storage systems,taking into account the energy and ancillary services markets.This was used to drive the financial and resilient value of distributed energy and to identify key factors such as the distributed energy mix,as well as the pricing structure of electricity and natural gas distribution companies.The conclusion has been obtained that different types of energy tariffs will affect the financial aspects of distributed energy projects.In addition,the results highlight the key role of energy storage system incentive programs in increasing grid resilience during outages.
