Southern power grid hainan power grid companies to invest 6.76 million yuan to build the first "scenery ChuChong change" centralized charge of hainan province officially put into operation recently in haikou coconut sea avenue in power station, magnified by the wind, light, store can complementary effect, electric vehicle charging orderly and coordinated control solutions, form can be copied can promote new energy + charging infrastructure integration operation mode.
"Last year, the number of new energy vehicles in Hainan exceeded 64,000, and a large number of electric vehicles were connected to the power grid for charging, which will further aggravate the peak-valley difference in electricity load." China Southern Power Grid Hainan Power Grid company new business department evaluation department staff zhang Lulu said.
According to statistics from the Provincial Department of Industry and Information Technology, by the end of 2020, the province had built a total of 22,000 charging piles, 916 public charging stations and 12 power changing stations, with the overall car-pile ratio reaching 2.4:1, better than the overall level of the country. The number of new energy vehicles in the province is over 64,000, ranking fourth in China. The promotion of new energy vehicles has increased by 142.5% year on year, and the Development Plan for Clean Energy Vehicles in Hainan province has been accelerated.
"The rapid growth of electric vehicles in Hainan has brought the pressure of large-scale increase in charging load. We focused on the organic integration of electric vehicles and new energy with the power grid and carried out active pilot projects." Zhang Told Hainan Daily that in 2020, Hainan Power Grid Company invested 6.6786 million yuan to upgrade haikou Longhua Charging and changing Power station, including building nine 60-kilowatt integrated charging piles, a 500-kilowatt / 1MW-hour prefabricated cabin energy storage system, a 40-kilowatt photovoltaic power generation system and a 10-kilowatt wind generator. It has independently developed a platform for the integration of electric vehicles and new energy and power grid, effectively transforming the technological achievements of solar energy storage, charging and switching, multi-energy complementing, and source network load interaction, and built Longhua Charging and changing Station into a demonstration pilot for the complementary application of wind, light and multi-energy storage.
Learned, longhua pump in power plant through "optimal" economic dispatching station control strategy, 0 to 5 PM every day from the landscape system and power grid to the energy storage batteries, electric vehicle power supply, 8 to 16 by landscape system and power supply, 16 and 22 by the scenery and energy storage system power supply, other times by a landscape system and power supply, It realizes the spontaneous self-use of distributed energy in the station and the Internet access of surplus electric energy, amplifies the multi-energy complementary effect, effectively reduces the cost of electricity in the station and comprehensively improves the operation efficiency of the charging and changing station.
Since put into operation at the end of last year, so far, the site of electricity to 265900 KWH, power saving of 28000 KWH, energy-saving proportion is as high as 10.5%, built the electric vehicle charging orderly and coordinated control of hainan samples, the future is expected to continue to copy the promotion, for all types of hainan industrial park comprehensive energy services provide a platform to support.
