Advanced Pinch Algorithm Geared to Smart Grid Area Used for Multi-energy Recycling

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。

Based on the characteristics of cooling,heating,electric,mechanical loads,and illumination in the smart grid area, the best optimization value is put forward by making use of the fundamentals of the pinch algorithm while considering the properties of electric power itself.When heat-exchange network is analyzed,kW is used as the unit of measurement in equations of all kinds of energy to promote graded use of multi-energy.A multi-energy optimization analysis method based on the improved pinch algorithm is proposed,with which both the lowest value of theoretic energy consumption and improvement ideas of multiple energy utilization can be achieved.What”s more,this method can be applied in many kinds of user in smart grid area,such as industry,public institution,data center and so on.
