Mandatory Primary Frequency Response (PFR) in Australian Power Grid

With the increasing penetration of renewable generation (e.g., wind, solar PV) in the Australian power grid and planned retirement of large conventional thermal will potentially result in deteriorated frequency regulation performance due to the reduced system inertia and primary frequency response. Until recently, synchronous generators (e.g., coal, gas, and hydro) have provided PFR in the NEM and renewable energy generators were not expected to contribute to the frequency control of the grid. However, almost all the renewable generation is connected to the grid via power inverters. If these renewables are equipped with the necessary control features, inverter-coupled power generation technologies will also be capable of contributing to PFR. This capability can help alleviate the concerns around grid frequency quality and stability. The Australian Energy Market Commission (AEMC) has issued National Electricity Amendment on Mandatory Primary Frequency Response rules on 26 March 2020. In order to ensure sustainability in implementing mandatory PFR on Wind Power Plants, many technical aspects need to be considered, monitored, and managed. In this presentation mandatory, PFR, and the benefits and challenges around its implementation are discussed.
