Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.
[0029] The present invention uses the unit active power target value as the adjustment target and demarcation point of the conventional power supply unit and energy storage power supply unit, and then can conveniently carry out mechanism analysis and control on the combination of function blocks.
[0030] see figure 1 , a control method for conventional power sources and energy storage power sources based on charge and discharge correction power, through the complementary integrated power centralized control center to regulate and control conventional power sources and energy storage power sources:
[0031] The complementary integrated power centralized control center is provided with a complementary integrated unit, a conventional power supply unit, and an energy storage power supply un...

The invention discloses a control method for a conventional power supply and an energy storage power supply based on the charge and discharge correction power. The conventional power supply and the energy storage power supply are adjusted and controlled through a complementary integrated power supply centralized control center, and the complementary integrated power supply centralized control center is provided with a complementary integrated unit, a conventional power supply unit and an energy storage power supply unit, wherein the complementary integration unit sends the control operations including instructions for distributing unit active power target values to the conventional power supply unit and the energy storage power supply unit, and the unit active power target value of the energy storage power supply unit is updated according to the unit active power adjustment deviation of the conventional power supply in a fixed period. According to the present invention, the charging and discharging correction power is introduced into the active power target value of the conventional power supply unit, so that the conventional power supply serves as the charging and discharging source of an energy storage power supply battery to be flexibly adjusted, and meanwhile, the battery state balance requirement of each unit and the dynamic stability requirement of the active power in the adjusting process are considered.
Description
technical field [0001] The invention belongs to the technical field of electric power system automation control, and relates to a control method of a conventional power supply and an energy storage power supply based on charge and discharge correction power. Background technique [0002] Energy storage power supply is different from conventional power supply (firepower, hydraulic power) and new energy (wind power, photovoltaic power generation) power supply. Energy storage power supply does not have the ability to generate electricity (that is, independent power generation), but relies on battery storage systems and The charge and discharge control provides additional power storage and two-way (charge and discharge) regulation capabilities for the power system. Although it cannot produce electricity, thanks to its mechanism and characteristics, the energy storage power supply has incomparable technical advantages compared with conventional power supplies and new energy power...
