商业综合能源系统经济性分析

伴随电力价格管制的进一步放开，市场化电价对综合能源系统经济性的影响需要引起足够的重视。以北京地区某商业综合体为研究对象，通过分析该用能对象的冷、热、电负荷特性，提出适用的综合能源系统方案，建立起物理和数学模型，结合当前实施的中长期电力交易规则，以目录电价和市场化交易电价形成的价格信号对选择的能源系统展开经济性评价。结论认为，综合能源系统应该充分考虑到所处区域能源供应结构以及可能开展的市场化交易模式与规则和最终产品或原料价格大范围波动的可能性，并在设计初期提出可能的预案，最大限度降低实施综合能源系统后的无效化程度。

The influence of market electricity price signal on the economy of integrated energy system

With the further liberalization of power price control, enough attention should be paid to correctly dealing with the impact of market-oriented electricity price on the economy of integrated energy system. Taking a commercial complex in Beijing area as the research object, by analyzing the cold, heat and electric load characteristics of the energy consumption object, a suitable integrated energy system is put forward, and the physical and mathematical models are established. Combined with the current implementation of medium-and long-term power trading rules, the price signal formed by catalog price and market-oriented transaction price is used to evaluate the economy of the selected energy system. It is concluded that the implementation of an integrated energy system should fully take into account the regional energy supply structure and the possible market-oriented trading models and rules, and fully consider the possibility of large-scale fluctuations in the prices of final products or raw materials. The possible plan is put forward in the early stage of the design, minimize the ineffectiveness after the implementation of the integrated energy system.
