Description

technical field [0001] The present invention relates to the technical field of shared energy storage planning and configuration, and more specifically, to a shared energy storage planning method and system considering energy storage usage rights. Background technique [0002] The phenomenon of "double highs" and "double peaks" in the new power system has become more and more obvious, and the uncertainty at both ends of the source and load has increased significantly. The traditional "source follows the load" power balance adjustment method has been difficult to cope with the high proportion of new energy access. As a flexible and controllable regulating resource, energy storage can reduce the uncertainty of source load to a large extent, and plays an important role in improving the output characteristics of new energy, improving the stability of new power systems, and promoting the transmission and consumption of new energy. However, the cost of energy storage is still high ...

Problems solved by technology

Although this method guarantees the needs and interests of users, in order to meet the needs of users at the same time, multiple sets of batteries are used to provide charging or discharging services to users at the same time. Since there are a large number of users with different voltage levels in the energy storage system, and users often With internal multi-voltage level equipment and lines, once multiple groups of batteries provide charging or discharging services to such users at the same time, it is equivalent to connecting the electromagnetic loop of the transformer inside such users to form an electromagnetic ring network. The electromagnetic ring network is very important for the operation of the grid. The damage is huge; however, none of the existing technologies consider avoiding the appearance of the electromagnetic ring network in the planning of shared energy storage, which will bring great hidden dangers to the safe and reliable operation of shared energy storage and even the entire power grid, and even lead to system paralysis
