Demand Response Control Measures and Mechanism for Intelligent Electric Vehicles in Urban Distribution Network
The rapid development of new energy electric vehicles has an increasingly prominent impact on the supply and demand balance of urban distribution network and even the whole network.By analyzing the characteristics of new energy power generation and the power consumption characteristics of typical distribution network areas,the authors put forward the technical means of electric vehicle demand response,market and policy mechanism,vehicle pile administrative standard construction and other control measures,design three response modes of peak shifting and valley filling guidance,valley filling response charging and valley peak generation,and explore the demand response steps and control process of electric vehicles in distribution network.The power demand response of electric vehicles can minimize the periodic fluctuations caused by the difficulty of low-valley consumption caused by the randomness of a large number of new energy sources and the alternating operation of peak power supply shortages,reduce the impact of random charging of a large number of electric vehicles on the peak power consumption of urban distribution networks and the impact of heavy overload,increase the low-valley surplus power consumption capacity,reduce the cost of electric vehicles,improve the utilization efficiency of power generation,transmission and distribution equipment,and reduce the investment in fixed power construction.
