基于随机机会约束规划的冷热电联供微电网能量优化调度
Stochastic Operation of a Combined Heat and Power Microgrid
热电联供(Combined Heat and Power,CHP)型微网集成了多种分布式能源,能源利用率较高,具有光明的应用前景。科学合理的系统规划是CHP微网经济、高效运行的基础,基于此提出考虑需求侧热、电协同响应的CHP微网多目标规划方法,规划目标兼顾经济指标和碳排放指标。需求侧热电协同响应模型基于建筑物和热水箱的热力学特性,同时考虑可转移电负荷的调度。从而建立基于需求侧协同响应的CHP微网多目标混合整数线性规划模型。以居民区CHP微网规划为例进行算例仿真,验证了方法的有效性。结果表明,应用需求侧热电协同响应可降低CHP微网所需配置的燃气锅炉和储热罐容量,使系统具有更好的经济效益与环保效益。
英文摘要:
The Combined Heat and Power (CHP) type microgrid integrates a variety of distributed energy sources with high energy utilization and bright application prospects. Scientific and rational system planning is the basis of economic and efficient operation of CHP micro-grid. Based on this, a multi-objective planning method for CHP micro-network considering demand side heat and electricity coordination is proposed. The planning objectives take into account economic indicators and carbon emission indicators. The demand side thermoelectric co-response model is based on the thermodynamic properties of buildings and hot water tanks, while considering the scheduling of transferable electrical loads. Therefore, a multi-objective mixed integer linear programming model based on demand side collaborative response is established. Taking the residential area CHP micro-network planning as an example, the simulation of the example is carried out to verify the effectiveness of the method. The results show that the application of demand-side thermoelectric synergistic response can reduce the capacity of gas boilers and heat storage tanks required for CHP microgrid, so that the system has better economic and environmental benefits.
