“…Agents used to reduce conventional unit participation in daily load graph coverage [1]- [4]. RESs bring multiple benefits for EPSs and environment, but some of them, such as photovoltaic and wind power generators, have intermittent electrical energy production, which can produce frequency fluctuations [5]- [11].…”

The renewable energy sources (RESs) projects are solutions with environmental benefits that are changing the traditional power system operation and concept. Transient stability analysis has opened new research trends to guarantee a secure operation high penetration. Problems such as frequency fluctuations, decoupling between generator angular speed, network frequency fluctuation and kinetic energy storing absence are the main non-conventional RESs penetration in power systems. This paper analyzes short-circuit influence on frequency response, focusing on weak distribution networks and isolated, to demonstrate relevance in frequency stability. A study case considered a generation outage and a load input to analyze frequency response. The paper compares frequency response during a generation outage with a short-circuit occurrence. In addition, modular value and angle generator terminal voltage affectation by electric arc and network ratio R⁄X, failure type influence in power delivered behavior, considering fault location, arc resistance and load. The arc resistance is defined as an added resistance that appears during failure and influences voltage modulus and angle value results showing that intermittent non-conventional RES participation can lead to frequency fluctuations. Results showed that arc resistance, type of failure, location and loadability determine the influence of frequency response factors in weak power systems.

“…Actually, the discrepancy of frequency measurements at different locations can be observed in almost all events in multi-machine power systems, especially for largescale systems. Therefore, it is difficult to obtain the COI frequency and the rate-of-change-of-frequency (RoCoF) value for the whole system [35,36], although the system COI frequency and RoCoF are found to be very useful for many power system monitoring and control functions, which include under-frequency load shedding [37], frequency response analysis [19], frequency control [13], event magnitude estimation location estimation [17,38], transient stability improvement and fault-ride-through control [39], and resource size and location selection [40], etc. Some work has noticed the importance and challenges of obtaining the accurate COI frequency and RoCoF, and some has made some remarkable progress.…”

The power system frequency is important for the system overall stability. However, there does not exist a single measurement point of the system frequency due to the distributed nature of the system inertia and the small inconsistency of different generator rotors' electrical speeds in one synchronized system. This paper proposed a new approach to calculate the system center-of-inertia (COI) frequency and the rate-of-changeof-frequency (RoCoF) more accurately using PMU data at multiple locations. The COI frequency and the RoCoF value were further used to assist fast estimation of the imbalance MW amount of a frequency event. Test results using actual measurements in the U.S. Eastern Interconnection system validated the effectiveness of the proposed method.
