摘要：

能源市场管制放松的背景下,将能源价格作为一种可控资源,有望进一步推进区域能源中心(DEC)内电、气、冷/热等多种能源的优化运行。文中以能量枢纽为基础模型,提出了DEC功率平衡方程的通用线性化建模方法;同时,计及能源需求的价格弹性,对其进行分段线性化建模,并引入0-1变量及线性约束将分段线性函数的描述统一化。进一步,以DEC净收益最大化为目标,计及能源价格可控性,建立了DEC日前优化调度的混合整数二次规划模型,通过GAMS调用CPLEX进行求解。最后,以微网型DEC为例,验证了所提建模方法的有效性,分析了能源价格是否参与调控、不同价格弹性及新能源预测误差对调度结果的影响。结果表明,充分利用负荷的价格弹性,在最大化DEC净收益之余,有利于减小负荷方差和峰谷差,深度挖掘DEC的优化潜力。
