计及节能减排因素的配电网投资收益评价方法

Evaluation method for investment returns of distribution-network considering energy-saving and emission reduction factors

计及以新能源为主体的新型电力系统的建设和发展需求,构建绿色、高效配电网,提高投资效益成为包含可再生能源的配电网项目投资建设的关键问题。为保证配电网投资收益分析结果的合理性,在安全效能成本收益模型的基础上,提出计及节能减排因素的安全效能成本收益(environment safety efficiency cost benefit,ESECB)评价模型。通过结合配电网中典型馈线进行具体案例的投资收益评价,剖析影响投资收益的关键因素,并对该模型在实际应用中的可行性及合理性进行验证。

Considering the demands for the construction and development of new power systems with new energy as the main body,It′s a key issue to build a green and efficient distribution network and improve investment efficiency in the investment and construction of distribution network projects including renewable energy.In order to ensure the rationality of the investment return analysis results of the distribution network,an environmental safety efficiency cost benefit(ESECB)evaluation model was proposed considering the factors such as energy conservation and emission reduction based on the safety efficiency cost-benefit model.By combining typical feeder lines in the distribution network to evaluate investment returns of specific cases,the key factors affecting investment returns were analyzed,and the feasibility and rationality of the model in practical applications were verified.
