Uncertainty Analysis of Wind Power Fluctuations in Yunnan Power Grid
Abstract
The statistical analysis of wind power characteristics is the basic work of wind power integration research, and the statistical analysis method based on actual output data is the most direct and credible method to understand the characteristics of wind power fluctuations. Yunnan (a province in southwestern China) is rich in wind power resources. It is estimated that by 2020, the total installed capacity of wind power in Yunnan will reach 10 million kilowatts. Wind power output is characterized by volatility, randomness and intermittentness. As the penetration of wind power in the power grid is getting higher and higher, it will have an important impact on the stable and economical operation of power system. Based on the actual wind power output data of Yunnan power grid, this paper deeply studies and mines the uncertainty of wind power fluctuations in Yunnan power grid. The research results can provide important reference for power grid planning, scheduling, and wind power integration.
