Abstract

The invention provides a wind power output dispatching system and method jointly controlled by cogeneration and heating load, wherein the equivalent power generation and the system actual requirement are adjusted the same and the synchronization pressure is reduced via the joint control of the coal steam extraction and condensation type cogeneration set and the heating load; the heat is supplied in two modes of a hot water radiator and a hot pump power consumption, wherein the hot water is from the cogeneration set and the electricity is jointly supplied by the cogeneration set and the wind power generator set; under the condition of satisfying the electricity supply and the heat energy supply, the heating output hot water flow is reduced, the power consumption for heating is compensation, so that the electricity heat supply can supplement the insufficiency of the hot water heating and increase the load of the period of time of the electric power low. The wind power is adjusted according to the electricity load change and the wind power generation so that the adjusted wind power equivalent power has minimum difference with the actual needed wind power.

Description

technical field [0001] The invention relates to an urban comprehensive energy supply system, in particular to a method for realizing optimal control of a power system by scheduling heating loads. Background technique [0002] Renewable energy has the characteristics of green and clean, and has developed rapidly in recent years. But taking wind power as an example, while wind power provides clean and low-carbon energy, the large-scale grid connection of wind farms has also brought adverse effects on the safe and economic operation of the grid. Traditional scheduling problems are based on accurate load forecasting. However, wind energy is affected by various natural factors such as climate, altitude, terrain, and temperature, and has intermittent and random fluctuations. The difficulty of wind speed and wind power forecasting is much greater than that of load forecasting. Although scholars at home and abroad have done a lot of related research work on wind energy forecasting...
