Dispatching intermittent wind resources for ancillary services via wind control and its impact on power system economics

This paper focuses on assessing the effectiveness of wind control methods used to address the economic issues associated with higher penetration of variable (wind) generation. Two different wind control methods were implemented, namely maximum power limitation and delta control. Production costing simulations were done on IEEE 24 bus system with three wind farms, across different wind penetration levels to evaluate the impacts of wind control methods. Wind farms were allowed to participate in the ancillary service market while implementing the variable delta control. Results showed that these control methods have the potential to allow wind farm provide regulation or significantly lower regulation requirements, and reduce the overall production cost of the power system.
