Voltage Control Strategy for Distribution Area Microgrids Based on Improved Deep Reinforcement Learning Theory
分布式能源因其小规模且伴有波动性和间歇性的固有特性,给台区微电网的运行策略设计带来了显著挑战.尽管微电网系统成功地融合了多样化的分布式能源与外部电网,但其电压管理层面却日益复杂.鉴于此,提出了一种基于深度强化学习理论的台区微电网实时电压控制策略.首先,采用循环神经网络(RNN)模型,精准识别并处理系统内源荷功率数据中的损坏与缺失部分,确保数据质量.随后,综合考量了电能传输过程中的线路损耗以及电压越限的潜在风险,构建了台区微电网的电压管理模型.鉴于该模型内含复杂的非线性约束条件,采用了改进深度强化学习算法进行高效求解,通过ε-贪婪递减策略来指导智能体的动作选择,以克服传统方法的局限性.最后,为了验证所提策略的有效性和可行性,将本策略与传统控制策略进行对比测试,结果显示,提出电压控制策略在减小电压波动、降低网损等多个关键指标上均展现出显著优势.
The inherent characteristics of distributed energy resources(DERs),including their small scale,volatility,and intermittency,pose significant challenges to the design of operational strategies for distribution area microgrids.Despite the successful integration of diverse DERs and external power grids within microgrid systems,voltage management has become increasingly complex.In light of this,a real-time voltage control strategy for distribution area microgrids was proposed based on deep reinforcement learning theory.Firstly,a recurrent neural network(RNN)model was employed to accurately identify and handle corrupted or missing data in the source-load power data within the system,ensuring data quality.Subsequently,a voltage management model for the distribution area microgrid was constructed,comprehensively considering line losses during power transmission and the potential risk of voltage violations.Given the complex nonlinear constraints inherent in this model,an improved deep reinforcement learning algorithm was adopted for efficient solution,and an ε-greedy decreasing strategy was adopted to guide the agent's action selection,overcoming the limitations of traditional methods.Finally,to validate the effectiveness and feasibility of the proposed strategy,comparative tests were conducted against traditional control strategies.The results show that the voltage control strategy presented exhibits significant advantages in multiple key indicators,including reducing voltage fluctuations and minimizing network losses.
