论文摘要
我们提出了电流微电网的最佳操作控制策略。与现有工作相比，我们的方法通过操作具有可变流量温度的热网络来提高灵活性，并以这种方式明确利用其固有的存储能力。为此，微电网由由电气和热层组成的多层网络表示。我们表明，系统行为可以由DC功率流近似和1D不可压缩的EULER方程得出的离散时间状态模型表示。两层均通过热泵互连。通过将该模型与所需的操作目标和约束相结合，我们获得了受约束的凸优化问题。这用于推导一种模型预测控制方案，以实现电流微电网的最佳操作。在数值案例研究中证明了所提出的操作控制算法的性能。
We propose an optimal operation control strategy for an electro-thermal microgrid. Compared to existing work, our approach increases flexibility by operating the thermal network with variable flow temperatures and in that way explicitly exploits its inherent storage capacities. To this end, the microgrid is represented by a multi-layer network composed of an electrical and a thermal layer. We show that the system behavior can be represented by a discrete-time state model derived from DC power flow approximations and 1d incompressible Euler equations. Both layers are interconnected via heat pumps. By combining this model with desired operating objectives and constraints, we obtain a constrained convex optimization problem. This is used to derive a model predictive control scheme for the optimal operation of electro-thermal microgrids. The performance of the proposed operation control algorithm is demonstrated in a numerical case study.
