The invention belongs to the power system optimal scheduling field, and relates to an equivalent rescheduling determining method of a wind power acceptation cost. The method comprises steps as follows: firstly, a multiple power supply joint optimal scheduling problem is solved after wind power is considered on the basis of an optimization theory, and an optimal wind power output curve is obtained through calculation; secondly, the curve is subjected to equivalent electrical quantity and down load fluctuation conversion, and then rescheduling is performed; a rescheduling optimization process virtualizes the wind power into conventional power supply down loads for power generation, that is, other power supplies are excluded for matching to achieve power generation, and optimal scheduling is performed again; and finally, the acceptation cost spent by conventional power supplies on the wind power intermittent fluctuations is obtained by the aid of the difference between two scheduling results. The method can avoid interactive influences of complex coupling constraints, and the wind power acceptation cost is calculated quantitatively.
Description
technical field [0001] The invention relates to the field of optimal dispatching of power systems, in particular to a method for determining equivalent rescheduling of wind power acceptance costs. Background technique [0002] As a green and renewable energy, wind power has been greatly developed in countries around the world in recent years, and has become an important means for the world to deal with the depletion of fossil energy, environmental pollution, and climate change. However, wind power is different from conventional energy in that its primary energy is uncontrollable and intermittent. Therefore, when wind power enters the power system for consumption, conventional power sources are required to balance its intermittency, so as to ensure the real-time balance of the load supply and demand of the entire power system. [0003] As a result, when wind power enters the power system for consumption, in addition to the cost of wind power generation itself, it also requir...
