In this paper, the nonlinear economic model predictive control based energy management of a multi-energy microgrid is presented. The microgrid is composed of the district heating system with a cogeneration power plant supplying both the heat and the electricity demand of residential buildings with photovoltaic sources. Furthermore, access to liberalized heat and electricity market is assumed. This kind of environment requires consideration of the economical aspects, the technical aspects, the safety/quality of supply, and consumer preferences. The major contributions introduced in the presented approach are the following. A nonlinear formulation is adopted to capture the nonlinear thermal models and the nonlinear algebraic model of the heat supply network. The second major contribution is the economic character of the objective following the assumption of a liberalized market environment. Such formulation accounts for the specifics of the energy market organization. Finally, the stochastic nature of the planning problem is introduced through a practical robust formulation. The results obtained on a representative case study clearly show the benefits of the proposed approach compared to the traditional energy management approach.

基于鲁棒非线性经济MPC的多能源微电网管理

本文提出了一种基于非线性经济模型预测控制的多能量微电网能量管理系统。微电网由区域供热系统和热电联产发电厂组成，该热电联产发电厂利用光伏源为住宅建筑提供热量和电力需求。此外，假定进入自由化的热电市场。这种环境需要考虑经济方面，技术方面，供应的安全性/质量以及消费者的偏好。提出的方法中引入的主要贡献如下。采用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。第二个主要贡献是在假定市场环境自由化之后目标的经济特征。这样的表述考虑了能源市场组织的细节。最后，通过实用的鲁棒公式介绍了规划问题的随机性。在具有代表性的案例研究中获得的结果清楚地表明，与传统的能源管理方法相比，该方法的好处。
