Guaranteeing the provision of primary frequency control services by distributed generation

Abstract

In this work, a tool for the evacuation of Primary Frequency Control (PFC) service by generators connected to the distribution network is proposed. To achieve this goal, a linear AC Optimal Power Flow (OPF) model with a minimization objective and generation re-dispatch constraint is developed to guarantee the provision of the control service. Tests are carried out on an 8-bus system and a real High Voltage (HV) distribution grid. The obtained results revealed that the algorithm can guarantee the provision of the required PFC service provision by re-dispatching the connected generators while at the same time satisfying other operation and network constraints.
