Abstract: Due to the high uncertainties of renewable energy, the power supply-demand balance state shows new features in Northwest power grid. The power grid faces big challenges in both renewable energy accommodation in low load period and reliable power supply in peak load period. This paper firstly evaluates the characteristics of power supply-demand imbalance risks in Northwest China, according to the actual operation data and historical statistical data. Then, the key technologies and supporting market mechanisms for regional power supply-demand balance in China and abroad are reviewed. Based on the development trend of grid-source-load in Northwest China, some measures and suggestions are proposed for power supply-demand balance in Northwest power grid to guarantee the reliable supply of electric power and efficient accommodation of renewable energy.

Key words: renewable energy accommodation, power supply-demand balance, power system with high proportion of renewable energy, electricity market
