摘要

利用可再生能源发电的热电联产系统(CHP)具有运行效率高、成本低的特点,是微电网的一种重要形式。本文研究了包括风能、光伏、余热锅炉和蓄电池在内的热电联产系统的经济运行问题。在预测未来24小时风电、光伏发电、电力、热需求的基础上,建立非线性优化模型,处理可用电力资源的经济运行,制定24小时工作计划。此外,本文还重点研究了电池电价和峰谷电价对系统运行成本的影响。对热电联产试验系统的四种不同情况进行了比较。试验结果表明,峰谷电价会增加系统运行成本,而采用蓄电池和调峰可有效降低系统运行成本。

Microgrid economic optimal operation of the combined heat and power system with renewable energy
Combined heat and power system (CHP) with renewable energy generation, which operates with high efficiency and low costs, is an important form of microgrid. This paper deals with the problem of economic operation of cogeneration system including wind energy, PV, heat recovery boiler and battery. On the basis of predicting the next 24-hours' wind energy and PV power, power and heat demand, a nonlinear optimal model is built to deal with the economic operation of available power resources and formulate the 24-hours' work schedule. Besides, this paper focuses on the effect of battery and peak-valley electricity price on system operation costs. Four different cases with a test CHP system are compared. Test results indicate that peak-valley electricity price would increase the system operating costs, while using battery and peak load shifting can effectively reduce operating costs.
