Data-driven Online Voltage Regulation Strategy for Low-voltage Active Distribution Networks
摘要
Abstract
Low-voltage active distribution networks with a high proportion of rooftop photovoltaic face severe overvoltage issues.Simultaneously,the lack of topological structure and line parameters further complicates voltage optimization and regulation.To address this,a data-driven online voltage regulation strategy is proposed.First,a data-driven method is employed to online identify and update the parameters in the system node voltage-power equation,providing a foundation for dynamically estimating node voltages.Then,a voltage optimization and regulation model aimed at maximizing photovoltaic accommodation is established.Based on the model solution results,while controlling the photovoltaic inverters to track reactive power commands,dynamic limiting of active power output is implemented to achieve effective voltage regulation.Case results demonstrate that this strategy not only resolves the issue of node voltage estimation without an electrical model but also effectively achieves overvoltage mitigation following the principle of reactive power priority,maximizing photovoltaic accommodation and validating the effectiveness of the proposed strategy.关键词
