针对微电网孤岛运行模式下新能源发电强随机性导致的系统频率波动，本文提出了基于多智能体相关均衡强化学习(Correlated Equilibrium Q(λ), CEQ(λ))的微电网智能发电控制方法。在所搭建含有光伏发电、风力发电、小水电、微型燃气轮机和飞轮储能的微电网负荷频率控制(Load frequency Control, LFC)模型基础上，以频率偏差作为状态输入，提出了一种微电网孤岛运行模式下的CEQ(λ)智能发电控制器。仿真结果显示，与PI控制、单智能体R(?)控制相比，CEQ(λ)控制器具有更好的在线学习能力，能显著增强孤岛微电网的鲁棒性和适应性，有效提高了频率的考核合格率。
英文摘要:
This paper, to address frequency fluctuate problem of the islanded micro-grid caused by strong randomness of renewable energy, proposes a smart generation control method of micro-grid based on multi-agent correlated equilibrium Q(λ). After establishing the micro-grid load frequency control (LFC) model containing photovoltaic generation, wind turbine, small hydro unit, micro gas turbine and flywheel energy storage, which takes frequency deviation as the input, a smart generation controller based on correlated equilibrium Q(λ) has been proposed. Simulation analysis, compared with PI controller, R(λ) learning controller, shows that correlated equilibrium controller has better pre-learning ability, and enhances robustness and adaptability of islanded micro-grid remarkably and improves the frequency assessment pass rate effectively.
