1 Introduction In recent years, China''s new energy storage applications have shown a good development trend; a variety of energy storage technologies are widely used in
Actually, China power system has already over capacity, and peak load is 980 [GW], at this point the reliability index is hardly change. In order to continue the research, choose the peak load as 1050 [GW] to continue the follow simulation (Figs. 10, 11). LOLE with variation results under varying peak load
For instance, power system reliability can be affected by the high penetration of large-scale wind turbine generators (WTG). Therefore, energy storage system (ESS) is usually installed with the distributed renewable energy generation to improve the power system reliability by smoothing out the fluctuations and improve the supply and demand balance.
This paper aims to analyze the power system reliability by developing the multi-ESSs coordinated with WTGs model, which is each ESS linked with each WTG. The main indices for reliability evaluation are loss of load expectation, expected energy not served and energy index of reliability. Monte Carlo simulation method is used in this study.
After rapidly develop of China’s electrical industry over the last decade. The China’s electricity supply condition has been changed from a shortage electricity to an oversupply phenomenon. By the way, the imbalances in supply and demand condition are likely continue for the next decade.
In this research, the reliability of a power system involving WTG and multi-ESSs can be evaluated using a basic model and algorithm. By using the proposed model, the reliability analysis of WTG with multi-ESSs can be obtained. Suitable capacity of WTG and multi-ESSs can be determined and used efficiently for a sensitivity analysis from the result.
When the system is fully supplied, it will store energy and release it when the power system is stationary . The power system reliability is the ability of the power system to continuously provide sufficient and high quality electricity to electricity power consumers. The reliability of power systems can be measured with reliability indicators.
