The invention discloses an optimization method of an active power dispatching conservative factor of a power system, relates to the technical field of power system operation, and aims at solving the technical problem that the optimality of an optimization result of an active power dispatching optimization model of the power system cannot be ensured by the artificially given active power dispatching conservative factor of the power system. The optimization method of the active power dispatching conservative factor of the power system comprises the steps of building an active power dispatching model, including wind power, of the power system; obtaining an active power dispatching scheme of the power system according to the active power dispatching model of the power system; building a multi-objective optimization model for the active power dispatching conservative factor of the power system according to the active power dispatching scheme of the power system; and obtaining the optimal conservative factor of active power dispatching of the power system through an optimization algorithm according to the multi-objective optimization model.
Description
technical field [0001] The invention relates to the technical field of power system operation, in particular to an optimization method for the conservatism degree of active power dispatching of the power system. Background technique [0002] Wind energy is a green and environmentally friendly renewable energy, and the development of wind power is conducive to improving the energy structure. However, due to the uncertainty of wind power output, it will have a great impact on the active power dispatching of the power system. For example, during the low load period, if the wind power output fluctuates greatly upwards, the insufficient down-regulation capacity of conventional power sources will cause wind curtailment losses; while during the peak load period, if the wind power output fluctuates greatly downwards, the insufficient up-regulation capacity of conventional power sources will cause Cause power loss; in addition, the uncertainty of wind power output may cause the powe...
