Local Self-Made Interactive Strategy for High Proportion of Vehicle-Optical Access Distribution Network for Vehicle-Optical Collaboration
Abstract
This paper studies the local self-made interactive strategy for electric vehicles and photovoltaics connected, aiming to optimize operating network through the vehicle-light collaboration mechanism. As a distributed synergy between electric vehicles and photovoltaic power generation can provide regulation when the grid load fluctuates, improving the reliability and economy of the distribution network. Experiments show that the photovoltaic power output has a significant impact on the response of distribution network load. When the photovoltaic penetration rate increases from 10% to 25%, the photovoltaic output of the system reaches 8.2 MW at noon, and increases by 137% at lower penetration rates. During the peak load at night, the photovoltaic power output drops sharply, causing the equivalent load of the system to surge by 19.3%. By introducing a dynamic reactive power compensation device, the power factor of the photovoltaic inverter is increased from 0.95 to 0.98, which can effectively smooth the voltage fluctuation of the photovoltaic output to the power grid. Based on the above data analysis, the local self-made interaction strategy of vehicle-light collaboration proposed in this paper can achieve a high proportion in the context of renewable energy access, optimizing the dispatching and interaction of electric vehicles and photovoltaics not only effectively reduces power grid load fluctuations, but also improves the operating efficiency and reliability of the system. Especially under the high proportion of access, a reasonable dispatching strategy can balance to the maximum extent, reduce energy loss, and enhance the anti-interference ability of the power grid.
