| Popis: | This paper focuses on the effect of wind farm stochastic power variability on the voltage stability support to a real power system. An emergency maximum reactive support (EMRS) control strategy is considered, with the help of which wind farms can contribute in increasing the power transfer limit in a weak part of a transmission system. In order to generate realistic synthetic wind power data, a Markov model with low complexity is chosen and implemented to simulate wind power generation. Wind farm feeder characteristics and MV/HV substation controls, such as feeder resistance and reactance, switched capacitor banks and load tap changer controls, as well as wind farm converter voltage and current limitations are modeled in detail. Different scenarios, initiating from a historic insecure snapshot in an area of the Hellenic interconnected system, are used to assess the impact of stochastic wind farm generation on the contribution of the maximum reactive support control scheme on voltage stability. |
