Backpressure heat and power cogenerator and wind power generator output heat supply scheduling system and method

Abstract

The invention discloses a backpressure heat and power cogenerator and wind power generator output heat supply scheduling system and a backpressure heat and power cogenerator and wind power output heat supply scheduling method. Through the combined control by a backpressure heat and power cogenerator unit and a heat generating load, the equivalent power generated by a wind power generator is regulated to be consistent with the actual needs of the system, and thus, the grid-connection pressure is reduced. A user adopts two heat supply modes, namely a hot water radiator mode and a heat pump power consumption mode, wherein the hot water is supplied by a heat and power cogenerator unit and the power is supplied by both the heat and power cogenerator unit and a wind power generator. The warming output hot water flow is reduced under a condition that the power supply and heat supply are satisfied, and the heat is compensated for by consuming power; the power-consuming heat supply can overcome the drawback of hot water warming and increase load in a power trough period; and regulation is performed according to the change of a power consumption load and wind power generation cooperation, so that the wind power equivalent power after regulation is most close to the actually need wind treatment.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of clean energy, and relates to a back pressure cogeneration unit and wind power output heat supply scheduling system and method. 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 ...
