초록
The Jeju-Korea power system is a small-sized network with a system demand ranging from a autumn minimum of 350㎿ to a summer peak of 716㎿. Because Jeju island is well exposed to north-east winds with high speed, applications to connect to Jeju power system are flooded. Considering physical/environmental constraints, Jeju Self-governing Province has also target for the wind power capacity of 1,350㎿ by 2020. It amounts to two or three times of Jeju average-demand power and wind power limit capacity announced by Korea Power Exchange(KPX) company. Wind farm connection agreements will be signed to maximize utilization of wind resource. In spite of submarine cable HVDC connected to Korea mainland, Jeju power system is independently operated by frequency and reserve control. This study reevaluates wind power limit based on the KPX criteria from 2016 to 2020. First of all wind power generation limit are affected by off-peak demand in Jeju power system. Also the possibility capacity rate of charging wind power output is evaluated by using energy storage system(ESS). As a result, in case of using 110㎿h ESS, wind power limit increases 33?55㎿(30?50% ofESS), wind power constraint energy decreases from 68,539㎿h to 50,301㎿h and wind farm capacity factor increases from 25.9 to 26.1% in 2020.
Abstract
The Jeju-Korea power system is a small-sized network with a system demand ranging from a autumn minimum of 350㎿ to a summer peak of 716㎿. Because Jeju island is well exposed to north-east winds with high speed, applications to connect to Jeju power system are flooded. Considering physical/environmental constraints, Jeju Self-governing Province has also target for the wind power capacity of 1,350㎿ by 2020. It amounts to two or three times of Jeju average-demand power and wind power limit capacity announced by Korea Power Exchange(KPX) company. Wind farm connection agreements will be signed to maximize utilization of wind resource. In spite of submarine cable HVDC connected to Korea mainland, Jeju power system is independently operated by frequency and reserve control. This study reevaluates wind power limit based on the KPX criteria from 2016 to 2020. First of all wind power generation limit are affected by off-peak demand in Jeju power system. Also the possibility capacity rate of charging wind power output is evaluated by using energy storage system(ESS). As a result, in case of using 110㎿h ESS, wind power limit increases 33?55㎿(30?50% ofESS), wind power constraint energy decreases from 68,539㎿h to 50,301㎿h and wind farm capacity factor increases from 25.9 to 26.1% in 2020.
