Abstract

Abstract: The environmental problem caused by fossil energy consumption is increasingly prominent. To replace the fossil energy with clean energy is the inevitable requirement of ecological civilization construction. The clean energy in China is mainly concentrated in the north and western regions, where the clean energy is difficult to be consumed locally due to the low electricity demand, and it is necessary to optimize the energy allocation in the whole country. Based on an analysis of the supplementary characteristics of wind, photovoltaic and hydro power in China's western region in view of the renewable energy features, this paper studies the benefits of multi-energy coordination to reduce the intermittency, randomness and fluctuation of renewable energy. A sequential power system operation simulation technique is proposed considering the network constraints and the random characteristics of renewable energy sources. A simulation is made on the large scale development scenario of clean energy in northwest China, and the results show that construction of interconnection transmission channels between northwest and southwest regions can realize multi-energy coordination, improve clean energy power quality, and raise the utilization efficiency of clean energy transmission lines.

Key words: clean energy, power planning, multi-energy coordination, wind power, photovoltaic, hydropower
