Research On Power Adjustment Strategy And Control System For Distributed Photovoltaic Power Generation

This paper analysis the in recent years at home and abroad a large amount of distributed photovoltaic power generation network of power grid development trend, for after the rapid expansion of domestic distributed PV, the end of the network by pure receiving end grid transformation for power, electrical integration of the smart distribution grid proposed distributed photovoltaic power plant root according to power grid dispatch generation Internet control target value of voltage regulation and target value of active power and reactive power control strategy, and the corresponding control system is studied.Active power control is used to control the target in the control of power generation. The voltage control takes full account of SVG(SVC), photovoltaic inverter, main transformer and other reactive power regulation resources, and integrated public connection point voltage, power factor and power factor. Through the research of strategy analysis and control system, a fast, economical and accurate method is found to be applied to the grid generation control and voltage control.
