Problems solved by technology
However, due to the limitations of the current electrochemical energy storage technology, the energy storage power supply is still unable to realize power storage in the true sense, but can only be used as an auxiliary adjustment method, which is still restricted by the problem that clean energy and meteorological resources cannot be stored.

The invention discloses an active power control strategy for networking of an energy storage power supply and clean energy. The energy storage power supply and the clean energy are subjected to coordinated control through a complementary integrated power supply centralized control center; the complementary integrated power supply centralized control center is provided with a complementary integrated unit, an energy storage power supply unit and a clean energy unit; the complementary integration unit sends an instruction for distributing a unit active power target value of the energy storage power supply unit to the energy storage power supply unit and the clean energy unit, and an instruction for generating an on-off operation suggestion of the clean energy power supply unit; therefore, adjustment requirements of a total active power set value and primary frequency modulation of a complementary integrated power supply composed of an energy storage power supply and clean energy and charging and discharging requirements of an energy storage power supply battery are met. According to the invention, the battery state parameters of each unit of the energy storage power supply are introduced for adjustment, the overall sensitivity of the overall control strategy is inhibited, and the combination of clean energy and the energy storage power supply is realized to realize good economical efficiency and stability.
Description
technical field [0001] The invention belongs to the technical field of electric power system automation control, and relates to an active power control strategy for networking an energy storage power supply and a clean energy source. Background technique [0002] With the implementation of the new energy strategy, the proportion of clean energy in China's power grid continues to increase, but the clean energy power station mainly composed of photovoltaic power generation and wind power generation "depends on the weather", and its power generation capacity strongly depends on the weather that cannot be adjusted and stored Resources, with strong randomness and volatility characteristics, seriously threaten the security of the power grid, especially wind power, because of its inverse peak-shaving characteristics, which are completely opposite to the peak-valley of power generation and peak-valley of power consumption, it is even called "garbage power" in some occasions .
