Based on the research of electric vehicle energy storage stabilization, stochastic, adjustable, robust optimization, wind-solar complementary intelligent water pump system service double carbon,Which aims at: (1) In order to promote the consumption of wind power and photovoltaics in the grid, and reduce the pressure on the load of the distribution network;（ 2) Consider wind power and photovoltaic output fluctuations and electric vehicle cluster energy storage systems, and use multiple electric vehicle clusters to coordinate and smooth tie-line power fluctuations. The model includes: (1) a load monitoring terminal; (2) a server for storing, processing and mapping all collected electrical energy data; (3) a set of user-centric electrical energy management visualization and prediction services. (4) A set of photovoltaic water pumps, pumped energy storage systems and electric vehicles for supplying water to impoverished areas . Experimental data and practical applications show that because the wind and wind have a certain degree of complementarity, but are greatly affected by the climate, pumped energy storage and electric vehicles can reduce the volatility of the system. The research results show that photovoltaic and wind power have great volatility, and the current investment and operating costs of energy storage systems are relatively high. Large-scale deployment of energy storage systems will seriously affect the economics of photovoltaic and wind power into the grid. It is recommended that users can transfer part of the daily electricity load on Saturdays to Monday to Friday. The results also show that the wind and solar complementary system can improve the utilization of wind and solar energy, form a good complementarity, and the efficiency of the system is improved by 1.24%. The addition of the wind-solar electric vehicle energy storage system has a certain impact on the operating cost of the system, and the grid-connected capacity is inversely proportional to the cost. When only thermal power is involved, the total operating cost of the system is 15.103 million yuan, and the total operating cost of the system after adding the wind-solar electric vehicle energy storage combined system is 876,000 yuan, and the total operating cost has dropped significantly. The power generation cost of wind turbines and pumped energy storage units is very small and can be ignored. The main cost of the system is the coal consumption cost of thermal power units and the start and stop costs of pumped energy storage units. After the combined wind storage system is added, the output of thermal power units in each period will be reduced. Small, the corresponding coal consumption is significantly reduced, so that the operating cost corresponding to each time period is significantly reduced.The overall situation is satisfactory. This paper studies the impact of thermal power units on carbon emissions, and the significance of energy transition and electric energy management to China's carbon neutrality . Every 1 kilowatt-hour of electricity replaced by a traditional thermal power unit is equivalent to saving 0.4 kilograms of coal energy and 4 liters of purified water. At the same time, it also reduces 1kg of carbon dioxide and 0.03kg of sulfur dioxide emissions. Liu Zuming’s team built the world’s first megawatt-level photovoltaic water pumping system. Take this as an example to calculate. Based on 5000 kWh a day, it can reduce 5 tons of carbon dioxide emissions per day. According to photovoltaics, they can be used for 20 years, at least. Can reduce 36500 tons of carbon dioxide emissions. In addition, his team has built more than 160 photovoltaic power plants in the Yunnan Plateau, which can have a longer-term and comprehensive impact on carbon emissions. Jiangyi Township’s emergency water supply for drought relief and rural drinking water safety consolidation and improvement of the project’s annual water supply The volume is 410,800 m3, covering 6 village committees and 41 natural villages in Jiangyi Township, Jiangyi, Painter, Banqing, Gongcha, Horizontal Stone, and Nuolakun, and solves the problem of safe drinking water for 11,590 people and 3140 large livestock in Jiangyi Township. problem. In conclusion, the experimental evidence introduced in this article supports that the random adjustable robust optimization of wind-solar complementary smart pump home energy management system is feasible and valuable for residents in poverty-stricken areas and China, and the impact of energy transition on China's carbon neutrality is significant and far-reaching.
