Research on power supply ratio scheme of source network charging and storage project under the dual carbon target

Energy is an important material basis for economic and social development, and energy security is an important part of national security. China strives to reach the peak of carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060. Therefore, in the next development, China will build a new power system with new energy as the main body. The realization of multi-energy complementarity and the promotion of the integration of source, grid, load, and storage are conducive to the construction of a clean, low-carbon, safe and efficient energy system. This paper selects the actual source network load storage integration project as a case to study how to use the regional resource endowment to select the optimal source network load storage project power ratio scheme. First of all, this paper studies the multi-source complementary characteristics of the power side of the integration of source, network, load, and storage with new energy as the main source under the dual carbon target, that is, stationarity, probability distribution characteristics, complementarity, reliability and load matching degree, and studies the on-grid power of the power side. Secondly, according to the actual source network charging and storage project, five power supply schemes are put forward, and the abandonment rate and the proportion of new energy power of each scheme are defined. The power system operation simulation software SPER_ProS2013 to carry out the simulation analysis of different schemes, and calculate the main calculation indexes of each scheme; Finally, through the simulation calculation of production operation, from the economic point of view, the power ratio scheme 1 is selected. The scheme can make full use of the new energy resources in the agglomeration area and its surrounding areas, effectively increase the proportion of clean energy consumption in the agglomeration area, and help the region to achieve the "30.60 targets" as soon as possible.
