| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 102 === Rapidly growth of wind power sector present great challenge for power system operator. These challenges include the ability forecasting wind out- put, manage frequency and voltage variability, as well as ancillary market. Nowadays, through different set of control possibility, wind power plants are able to partly participate in provision of ancillary market.
Traditionally, ancillary market is supported by a lot of conventional generators. However, in recently years, with the penetration of new wind generations (Double Fed Induction Generator (DFIG) and Direct Drive Synchronous Generator (DDSG)) and through different set of control possibility, wind power plants are able to partly participate in provision of ancillary market. This thesis study the method to calculate price of reactive power with the purpose support wind farm provide reactive power in order to increase voltage stability for power system based on Optimal Power Flow, Locational Marginal Price and the loss of active power. This study used the Power World Program to simulate wind generator (DFIG) and calculate locational marginal price. 9-Bus_system is used to show the change of benefit of wind generator when the increasing load is applied.
