Relationship Between Electricity and Renewable Energy Sources in an Aspect at “Carbon Neutrality”

East Inner Mongolia region is rich in renewable energy and is an important power station. The aim of this study was to further enhance the development and utilization of wind power and photovoltaic in the East Inner Mongolia region, and help build a new type of power system in the region. Based on the research targets in Chifeng, Tongliao, Xing’an and Hulunbuir in the East Inner Mongolia region, Study of load characteristics, wind power and photovoltaic output characteristics and optimal ratios throughout the year, and study the scale and mode of operation of energy storage in the banner county seats. Research shows that wind power, photovoltaic monthly output during the year as a whole shows the law of “winter big summer small, spring big winter small”, applies. Taking into account the operating costs and the average standard deviation of slow regions, the optimal ratio of wind and photovoltaic power in Chifeng should be 4.7:1, in Tongliao 4.8:1 and in Hulunbuir and Xing’an 4.4:1; Compared with the adjustment of the before energy storage method, the combined power formed by the power storage of grid is relatively gentle, with a low peak valley difference, and the overall performance of the grid side storage is better than that of the supply side storage. Therefore, research on the ratio of wind and photovoltaic power and the energy storage analysis of these regions can effectively promote the development of power and accelerate the realization of strategic goals such as “dual carbon”, as well as providing a reference for the future planning of the East Inner Mongolia region power network.
