Abstract

An embodiment of the invention provides a wind/light energy and hydropower unit combined regulation simulation system and a method at a transmission and reception end of a power network, The simulation system includes: wind/light energy model of transmission network and hydro-generator model of receiving network, wind/light energy model and hydro-generator model run together, and the fluctuation of target power output of wind/light energy model is compensated by hydro-generator model; The model of hydropower unit includes turbine model, diversion system model, hydrogenerator model and turbinegoverning system model. The turbine governing system model includes governor model and mechano-hydraulic servo system model. The simulation system provided in the embodiment of the invention developswind/light. Wide-area joint simulation of hydroelectric generating units. Under the background of large-scale new energy consumption difficulty, it provides a new way for UHV once-through hydro-generator units to absorb wind power across regions, which is of engineering application value to achieve cross-regional wind power consumption and improve the new energy consumption level of the whole grid.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of new energy consumption, and more specifically, relate to a simulation system and method for joint regulation of wind / solar energy and hydropower units in the power grid at the sending and receiving end. Background technique [0002] At present, renewable energy has broad development prospects due to its zero-pollution advantages, among which the use of wind energy, water energy, and solar power is developing most rapidly. Rational use of renewable energy to achieve sustainable energy development has become a major measure of energy development strategy. With the development of large-scale wind power / photovoltaic energy, the development of wind power / photovoltaic energy in my country has maintained a strong momentum of rapid development, but the contradiction between the unconventional development of new energy power generation and the relatively lagging power grid construction has be...
