Description

technical field [0001] The invention belongs to the technical field of new energy energy supply systems, and more specifically relates to a multi-energy complementary and stable energy supply system. Background technique [0002] Vigorously developing new energy is an inevitable choice to achieve the goal of "dual carbon", and it is of great significance for coping with climate change and promoting sustainable development. At present, the main problem of wind energy, solar energy, etc. is that the energy source is strongly dependent on weather conditions, and the output of wind power and photovoltaic power generation is highly volatile and discontinuous. After being integrated into the power grid, the pressure of peak regulation and frequency regulation of the power grid is increased, which seriously limits the large-scale use of new energy. develop. Energy storage technology is a key means to achieve coordinated energy management and optimal matching. At present, this tech...

Problems solved by technology

At present, the main problem of wind energy, solar energy, etc. is that the energy source is strongly dependent on weather conditions, and the output of wind power and photovoltaic power generation is highly volatile and discontinuous. After being integrated into the grid, the pressure of peak regulation and frequency regulation of the grid will be increased, which seriously limits the large-scale use of new energy. develop

Energy storage technology is a key means to achieve coordinated energy management and optimal matching. At present, this technology has not yet fully played a role in the new energy system, resulting in low energy utilization efficiency of the new energy system.

[0003] The current development of new energy has the following problems: wind energy and solar energy depend on weather conditions, and their power generation output is highly volatile and discontinuous, which is not conducive to grid connection; the current new energy system mainly uses a single energy storage form to store energy, which has not been fully utilized The peak-shaving and frequency-regulating functions of various energy storage technologies, the energy utilization efficiency of new energy needs to be improved
