摘要
随着新能源和化石能源互补的"混合能源时代"的发展,多种能源之间的协同互动成为解决工业园区能源结构不合理、电能利用率低的有效方法。以工业园区为研究对象,提出了一种考虑多能协同的需求响应模型。分析工业园区光伏发电和各类型负荷特征,建立了工业园区内储能和冰蓄冷空调的物理和数学模型,考虑源/储/荷协同运行策略,在分时电价下建立以工业园区运行费用最小为目标的优化模型,用混合整数线性规划进行求解。最后用算例表明多能协同在工业园区中具有较好的推广价值。
With the development of the‘era of mixed energy’with the complementary of new energy and fossil energy,the synergy interaction among multiple energy sources has been an effective way to solve the irrational energy structure and low power utilization rate of industrial parks.Taking the industrial park as the research object,a demand response model with multi energy coordination is proposed.The characteristics of photovoltaic power generation and various types of load in industrial park are analyzed and the physical and mathematical models of energy storage and ice storage air conditioning in industrial parks are established.Considering the coordinated operation strategy of source/store/load,the optimal model with minimum cost of industrial park is established based on TOU(Time-of-Use)price,and it is solved by mixed integer linear programming.Finally,a numerical example shows that multi energy synergy has a good promotion value in the industrial park.
