摘要(Abstract)：

热电联产机组(combined heat and power,CHP)传统"以热定电"的运行方式逐渐成为制约能源耦合系统发展的主要因素。以区域能源互联系统为对象,提出一种含电转气(power to gas,P2G)和热电解耦CHP的联合经济调度模型。首先,在CHP中引入有机朗肯循环系统打破热电耦合,通过电转气和CHP的协调运作提高系统经济性,同时兼顾系统间歇性清洁能源的消纳能力与环境污染的排放问题。其次,抽象出以系统用能成本和污染物治理成本之和最小为目标函数的数学模型,采用分段线性化和二阶锥松弛方法将模型线性化处理后对模型进行求解。最后,在IEEE-39节点电网与7节点天然气网耦合系统中进行模拟仿真,结果表明:在热电解耦运行方式下,CHP热电比优化控制对系统运行工况变化有较强适应能力;P2G能消纳多余风电,实现综合能源系统经济运行,降低排放。验证了所提模型有效性,可为区域能源互联网建设提供参考。
