微电网容量优化配置研究

Optimal Allocation of Microgrid Capacity

随着“双碳”目标的提出,就地消纳可再生能源的微电网将会得到大规模建设与广泛应用。合理规划微电网的容量配置具有重要意义。提出以微电网总成本最小为目标,建立微电网容量优化配置模型,采用粒子群优化算法求解。构建典型微电网并将其作为算例验证所提方法的有效性。优化计算结果表明,优化后的容量配置不但满足微电网的稳定运行需求,而且有效提高了系统的经济性。

With the proposal of the "double carbon" goal, the microgrid as the local consumption of renewable energy will be built on a large-scale and widely used. It is of great significance to plan the capacity allocation of microgrid reasonably. In this paper, with the goal of minimizing the total cost of microgrid, the optimal allocation model of microgrid capacity was established and solved by particle swarm optimization algorithm. A typical microgrid was constructed as an example to verify the effectiveness of the proposed method. The optimization calculation results show that the optimized capacity allocation not only meets the needs of stable operation of the microgrid, but also effectively improves the economy of the system.
