Problems solved by technology
Under the general pollutant discharge fee standard, compared with the economic growth rate, the increase in the price of sewage discharge is relatively small. When the cost of pollution reduction activities such as technological innovation and optimized management is much higher than that of sewage discharge charges, enterprises may not choose technological innovation. The phenomenon that the pollution reduction effect of enterprises does not increase but decreases

The invention provides a control method of photovoltaic output tracking environmental treatment load demand, and relates to the technical field of electrical engineering. The control method of photovoltaic output tracking environmental treatment load demand can realize that a photovoltaic power station can completely offset the mobile load of a heat-engine plant by making a flexible electricity price making mechanism by means of a pollution discharge charging model established in the environmental treatment background and other factors and calculating the transferred load capacity of the heat-engine plant under different electricity price according to the flexible electricity price making mechanism to compare the transferred load and the maximum controllable load fluctuation quantity of the photovoltaic power station, and by means of multiple regulation and control of a dispatching station. The control method of photovoltaic output tracking environmental treatment load demand can realize that the photovoltaic system tracks the transferred load from the heat-engine plant power grid in real time to avoid the power imbalance phenomenon, and can significantly improve reliability and economical efficiency of the electrical power system.
Description
technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a method for controlling photovoltaic output to track environmental governance load demand. Background technique [0002] With the in-depth development of my country's economic construction, environmental problems have become increasingly prominent, and more and more people have paid more and more attention to them. The power industry is a typical high-pollution and high-energy-consumption industry, especially thermal power plants. Pollutant emissions account for more than half of industrial pollution emissions. . Pollutant discharge charges are a common means used by the government to control pollution. Facts have proved that it is not enough to achieve energy conservation and emission reduction by simply charging power plants for sewage discharge to control pollutant discharge. It should also start from the user side, encourage users to purchase electricity gener...
