Embodiment Construction

[0027] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0028] The wind / storage integrated power scheduling plan optimization implementation method described in the present invention includes the following steps:

[0029] refer to figure 1 , step 1, use a discrete single wind turbine without an anemometer tower for trial operation, and the main input for power generation prediction is the wind direction, wind speed, humidity and pressure of the atmosphere at the point where the blade is located. The anemometer obtains the relationship between the regional numerical weather forecast value and the actual wind speed parameter of the wind turbine location, and the data relationship model is obtained by the multi-grid analysis algorithm based on finite element analysis, so as to obtain the weather forecast data of the short-term and ultra-short-term wind turbine installation points.

Abstract

The invention relates to the technical field of power system microgrid scheduling and particularly relates to a wind / storage integrated power scheduling plan optimization implementation method. The method comprises the steps that in the operation process of a discrete single wind generating set without an anemometer tower, the actual wind speed parameter relation between a regional numerical weather forecast value and the position of a fan is obtained in the trial operation stage, a data relation model is obtained through a multi-grid analysis algorithm based on finite element analysis, and weather forecast of short-term and ultra-short-term fan installation points is conducted; then, short-term and ultra-short-term wind power prediction is carried out by means of limited local weather forecast and experimental parameters of delivery of the wind turbine generator, fluctuation stabilization of generated power prediction is adopted as reported grid-connected power plan data, and the smoothness of grid-connected power fluctuation is guaranteed; a power plan deviation in real time is calculated by utilizing a lag inertia response of the wind generating set and a wind speed signal actually detected by a fan, an energy storage system is dynamically given, participation in dynamic compensation of the power plan deviation is realized, and the accuracy of a plan is ensured.

Description

technical field [0001] The invention relates to the technical field of electric power system micro-grid dispatching, in particular to a method for realizing the optimization of a wind / storage integrated power dispatching plan. Background technique [0002] Countries all over the world have been advocating the vigorous development and utilization of new energy technologies. The unstable output of wind power generation has brought great difficulties to grid-connected power generation. The large fluctuations of grid-connected wind power and the large deviations in planning and forecasting have always constrained the grid-connection of wind turbines. Successful realization of power generation. All countries in the world require that all installed capacity projects with super-high power must carry out power forecasting at 15-minute intervals. If the forecast error exceeds the limit, the wind farm must pay a fine to the power grid company. In my country, in order to standardize t...
