基于运行成本的园区综合能源系统优化调度

能源消耗密集型企业的聚集使得园区内部能源消费成本极高，且增加了电网运行稳定的不确定性，因此统筹配置新型能量转换设备的综合能源系统应运而生。文章提出综合能源系统的运行模式框图，并针对各设备的运行特性建立出力模型，以园区日运行成本最低为目标构建优化函数，并以各设备的额定运行状态为约束条件。基于改进蚱蜢优化算法的寻优结果显示配置了综合能源系统的工业园区在用能成本上有较大幅度的下降，且增加了对风光的消纳能力，具有较好的经济和环保效益。最后，将优化前后各部分运行成本进行对比，验证了文中所提方法的有效性和可靠性。

Collaborative optimal dispatching of integrated energy systems in industrial parks

The agglomeration of energy-intensive enterprises makes the cost of energy consumption in the park extremely high and increases the uncertainty of the stability of the grid operation. Therefore, a comprehensive energy system with the overall arrangement of new energy conversion equipment has emerged. The article proposes a block diagram of the operation mode of the integrated energy system, and establishes an output model according to the operating characteristics of each equipment, constructs an optimization function with the goal of the lowest daily operating cost of the park, and takes the rated operating state of each equipment as a constraint. The optimization results based on the improved grasshopper optimization algorithm show that the industrial park equipped with integrated energy system has a significant reduction in energy cost, and increases the ability to absorb the scenery, which has better economic and environmental benefits. Finally, the operation cost of each part before and after optimization is compared to verify the effectiveness and reliability of the proposed method.
