Congestion-induced wind curtailment mitigation using energy storage

摘要: Allowing the connection of additional renewable energy sources (RES) in areas with limited transmission capacity is becoming a serious concern. Building new lines only provides long-term solution to cope this issue due fact that it takes much longer time (up 5-10 years) compared needed build wind farms (about 1 year). Storage proven be an effective make maximal use existing grid infrastructures short-term. This paper proposes cost-benefit optimization formulation for optimally sizing storage wind-storage system which connected external spot market via lines. A small test studied order find optimal size avoid congestion by allowing revenue generated reducing congestion-induced curtailment. Additional streams can also included maximize monetary value system.
