基于风险的电力市场无功电源评估

Risk-based assessment for reactive power source in electricity markets

提出一种在电力市场中评估无功电源重要性的新方法:结合无功功率自身特点,根据无功电源对于系统安全的风险来确定无功电源的重要程度。其中,风险指标被用来描述各个无功电源的重要性。该指标能够有效地反映系统的不确定性以及由于无功出力变化所带来的后果影响。最后通过新英格兰系统的算例验证了该方法的有效性。

A novel approach to assess the importance of the reactive power sources in the electricity market is proposed, i.e. determining the importance of the reactive power sources based on their risk to system security. The risk index was used to describe the importance of every reactive source, and can effectively reflect the uncertainties of the system and the consequences of reactive source output variation. The effectiveness of the method is proved through the New England system.
