Empirical Study of Flexible Load Power Regulation Based on DC Bus Voltage in Photovoltaic Energy Storage Direct Flexible Systems
摘要
Abstract
The advantage of actively regulating the DC bus voltage in the photovoltaic energy storage direct flexible(PEDF)system to achieve communication-free control of flexible loads is significant,but its power regulation mechanism still lacks systematic modeling and optimization.Therefore,this paper proposes a flexible load power regulation mechanism based on DC bus voltage.It establishes the voltage-power function relationship and designs a voltage signal filtering method based on trend judgment within the limited sampling time.Through the verification of the photovoltaic future house DC community empirical platform,the flexible DC multi-unit load can achieve the perception and regulation of short-term and long-term voltage changes.The design of the filtering algorithm can filter out the voltage fluctuations caused by the operation of photovoltaic energy storage and short-term voltage steps while ensuring the dynamic response.This research provides an engineerable flexible load power regulation solution based on DC bus voltage for the PEDF system,as well as a certain data support for the standardization of the voltage-power regulation mechanism.关键词
