Research on large-scale intermittent new energy grid connected control technology based on power demand

Abstract

In recent years, with the increasing Power demand, new energy power has been continuously developed. As the main types of new energy power generation, wind power and photovoltaic power generation have strong randomness and correlation under the influence of natural conditions. The safe and efficient utilization of large-scale new energy power is the core content and basic goal of smart grid construction, while intermittent new energy is developing rapidly, there are also many problems. New energy resources and load centers show obvious reverse distribution characteristics. The fundamental reason that hinders the large-scale absorption of intermittent power in power grid lies in its randomness and volatility. It is necessary to study advanced prediction technology and control technology and make dynamic changes according to certain laws. The structure design of the new energy system of the large power grid can ensure that the power of wind, solar and other new energy can be connected to the grid to the maximum extent, the mathematical parameters and control strategies are correct and reliable, and the energy storage system can realize the dynamic tracking interaction with the power of the large power grid.
