Sažetak
Power system frequency response analysis is generally conducted on a single-area power system model due to fast and simple calculations. However, to obtain more accurate results of the system frequency dynamics, a frequency response analysis should be conducted on a multi-area power system model. In a multi-area power system, the frequency during disturbances can manifest itself differently in certain areas in the initial moments following a disturbance. As a result, generating units located in the distant areas contribute to the primary frequency control (PFC) with a certain time delay due to wave propagation. To overcome this issue, this paper introduces a novel method for a PFC mechanism. The main goal is to allow generators in remote areas to start changing the output power earlier, much before the wave propagates to that area. To achieve the desired result, the control of battery energy storage systems (BESS) during participating in PFC is modified to follow the tie-line power flow changes, while turbine generators of synchronous generators receive the frequency signal depending on the disturbance location area. To demonstrate the effectiveness of the proposed method, the results are obtained by simulating a three-area power system model.
