Abstract(s)

Frequency is the main parameter that reflects the stability of power system, and mismatches between generation and consumption. Increasing the penetration level of renewable energy resource in distribution network, and their noticeable participation level to provide the required electricity lead to a new challenge for the distribution system operators (DSO). The variable nature of renewable resources is inevitable, and this uncertainty can lead to instability of power systems. Therefore, DSO shall use more flexible and schedulable resource to maintain the security of network in the acceptable level. In this work, Demand response (DR) program is proposed as the backup resource for compensating the wind power uncertainty in primary frequency control (PFC). The proposed model specifies the required capacity of DR resource to maintain the frequency of grid in the allowable region, based on the uncertainty of wind generation. The performance of proposed model will be investigated by a case study.
