Combined-regulation simulation system and method of wind/light energy and hydro-generator set for transmission and reception end power network

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...

Problems solved by technology

[0004] Although there have been a large number of literatures in the prior art that have studied the feasibility of hydropower units in the receiving-end grid for compensating the power fluctuations of the sending-end grid and the dispatching operation of wind power and hydropower, but for the adjustment performance quality of joint operation in the process of hydropower compensation for wind power, hydropower There is a lack of in-depth research and discussion on unit output adjustment depth and adjustment speed, joint operation strategy, and joint operation simulation.
