Problems solved by technology

At present, the national economy is still developing at a high speed, the installed capacity and load scale of new energy are increasing rapidly, and the structure of the power system has changed greatly. If the refined production simulation of the power system with a huge amount of calculation is not carried out, and the time-series production simulation curve of new energy in the future years is obtained, then The current energy storage allocation calculation method cannot be carried out effectively, so it is impossible to provide scientific guidance for comprehensively evaluating the economy and rationality of energy storage power stations

[0004] The current energy storage allocation capacity calculation method has high requirements for time-series data. When calculating the energy storage allocation capacity in the next year, the existing energy storage allocation capacity calculation method, on the one hand, has a huge amount of simulation calculations for the refined operation of the power system, and on the other hand The data required for fine-tuning the simulation is also very large, and the calculation process is very arduous, so there is a problem of low calculation efficiency
