面向多主体的园区综合能源系统投资收益量化分析

新电改下园区成为电力改革重要实验区,在增量配电分开、多元源荷广泛接入情景下,园区综合能源系统投资界面出现了分化,投资主体呈现多元化特点,投资效益分析变得错综复杂。首先分析了新电改对园区综合能源系统运营的影响,基于不同投资分界面提出了4种运营模式,包括分布式电源发配售一体、分布式电源发售一体、配售一体和配网单营;其次构建了面向多主体的园区综合能源系统投资收益量化模型;最后根据实例案证,对比分析了四种运营模式下多主体投资收益计算结果。

Quantitative Analysis of Return on Investment of Park Integrated Energy System for Multiple Investors

Industrial parks have become important experimental areas for electricity reform in China. With the liberalization of incremental distribution market and widespread integration of diversified power sources and loads, the investment interface of park integrated energy system (IES) becomes divided, and the investment entities appear diversified. The analysis of investment benefits thus becomes more complex. This paper firstly analyzes the impact of electricity reform on the operation of park integrated energy system, and proposes four operating modes, including generation-distribution-sales integration, generation-sales integration, distribution-sales integration, and distribution network independent operation; Secondly, a quantitative return on investment model of park integrated energy system is presented for multiple investors, and a case study is conducted. Conclusions are given through a comparative analysis of the calculation results of multiple investors’ return on investment for the four operating modes.
