针对智能电网园区冷、热、电、机械、照明等多种负荷的特点,利用夹点算法的基本原理,结合电力自身特性,实现多类能源的综合分析,提出最佳优化值。在具体分析时,利用以千瓦为计量单位的换热网络,针对某些设备不包含流动介质的特点,结合各类能源的等值计算,推动多能源梯级利用。所提出的改进夹点算法,提供了一种多能源优化分析方法,既能从换热角度得到理论上的能耗最低值,又能为多能源优化利用提供一定的改进思路,适用于智能电网园区的工业用户、公共机构、数据中心等多种用户。
According to the characteristics of various loads such as cold, heat, electricity, machinery and lighting in the smart grid park, the paper uses the basic principle of pinch-in algorithm and combines the characteristics of electric power to realize the comprehensive analysis of various types of energy and puts forward the optimal optimization value. In the specific analysis, the use of heat exchange network in kilowatts as a unit of measurement for some devices does not contain the characteristics of the flow medium, combined with the equivalent calculation of various types of energy to promote multi-energy cascade utilization. The proposed improved pinch-in algorithm provides a multi-energy optimization analysis method, which can not only obtain the theoretical minimum energy consumption from the perspective of heat exchange, but also provide some improvements for multi-energy optimization and utilization, which is applicable to the smart grid Industrial Park, industrial users, public agencies, data centers and other users.
