2results about How to "Reduce wind curtailment rate" patented technology

This application discloses a wind turbine power conversion system and a control method for the wind turbine power conversion system, relating to the field of wind power technology. The wind turbine power conversion system includes: at least one wind turbine cluster, which is composed of several DC wind turbines connected in series, used to output electrical energy converted from wind energy in DC form; each DC wind turbine is equipped with a corresponding DC converter, and each DC converter is used to adjust its corresponding single-unit output voltage to maintain a balance among the single-unit output voltages formed by the DC wind turbines within the wind turbine cluster. By combining the DC wind turbine series structure with the voltage regulation capability of the DC converter, the problem of unbalanced output voltages of the wind turbines caused by wind power fluctuations is effectively solved, reducing the wind curtailment rate and improving the overall efficiency and stability of the wind power system.

The application discloses a kind of wind-fire-storage integrated energy system double-layer optimization scheduling method and device considering, belong to integrated energy dispatching field.The application is in view of the technical problems that single target energy storage scheduling optimization is difficult to consider economy and wind power consumption, energy storage capacity and operation constraint matching, adopts layered progressive optimization and collaborative iteration mechanism, upper layer constructs cost minimization day-ahead scheduling model, and solves fire storage wind output plan by mixed integer linear programming;Lower layer constructs the minimum correction model of wind curtailment rate, and dynamically corrects energy storage capacity and charge-discharge parameters by linear programming, and then the correction result is fed back to upper layer iteration optimization.The application realizes the dual target of system operation cost minimization and wind curtailment rate minimization, solves the adaptability and consideration difficulty of traditional dispatching scheme, improves the practicability and reliability of dispatching scheme, effectively promotes new energy consumption, gives full play to the role of fire storage collaborative peak shaving, and guarantees the safe, economic and stable operation of power system.
