摘要: 提出了一种基于非线性经济模型预测控制的综合能源微网能量管理方法。其中,微电网由集中供热系统和热电联产电厂组成,并利用光伏发电为住宅建筑提供热能和电力需求。此外,还假定其可以参加开放的热电市场。因此,在这种环境下其需要考虑经济、技术、供应的安全/质量和消费者的偏好。基于此,采用一种非线性公式来描述供热网络的非线性热模型和非线性代数模型,其次,是在假定有一个完全开放的市场环境之后,考虑目标的经济属性。最后,通过仿真研究,结果表明与传统能源管理方法相比,所提方法具有优越性。Abstract: In this paper, an energy management method based on non-linear economic model predictive control for integrated energy micro grid is proposed. The microgrid consists of a central heating system and a cogeneration plant, and uses photovoltaic power generation to provide heat and electricity power for residential buildings. In addition, it is assumed that the microgrid can participate in the open thermoelectricity market. In this situation the economy, technology, safety/quality of supply and consumer preferences need to be considered. Based on this, we first used a nonlinear formula to describe the nonlinear thermal model and the nonlinear algebraic model of the heating network. Secondly, we considered the economic attributes of the target after assuming a free market environment. At last, a simulation study was conducted and the results show that the proposed method is superior to the traditional energy management method.
