“…This is also because, being a centralized system, it will depend on communication links with their respective time stamps and latency [10]. To perform a fair comparison, an improved version of the AGC model proposed in [46] has been implemented. In this regard, it is important to highlight that this improved model already considers more realistic components of actual AGCs, such as: primary frequency regulation filters, and proper SCADA/EMS update and latency (around of 4–5 s) which causes a discrete and slower AGC response (a detailed description of this improved model will be presented in a future work).…”

This document presents a novel methodology to optimize the power system frequency response based on the implementation of decentralized controllers. The proposed method focuses on the control of the internal rotor angle in the selected generator, which allows its governor to act as a decentralized controller that requires as input local measurements. Through a proposed optimization process, it is first possible to establish a set of optimal parameters for each controller and, second, to determine the required phasor measurement units (PMUs) and their locations that are necessary to be installed in a power system. This comprehensive proposal is based on the time domain evaluation of the frequency response when multiple scenarios of deviations between demand and generation occur. Finally, the new proposal is applied to the IEEE 39-bus test system to validate its advantages; for this, the test power system as well as the proposed controllers are implemented in DIgSILENT PowerFactory, along with Python to manage the optimization process.

“…SCADA collects information related to system frequency, generator outputs, and actual interchange between the system and adjacent systems and AGC, by using this information, computes an Area Control Error (ACE). ACE specifies whether a system is in balance or needs to make adjustments to its generation [22,[26][27]. Therefore, AGC automatically determines the output for generating units by sending set-points to generators that participate in the AGC in order to restore energy balance and frequency control [28].…”

In this paper an extensive literature review of power system frequency control regulation and in relation to this, operating reserve determination policy have been highlighted. In terms of power system reliability and stability aspect, frequency control mechanism is the most important factor; hence there is a need for sufficient capacity reserve in case of contingency. An investigation of operating reserve policy in different regions, e.g., US, Canada, Europe and Asia have been conducted to clearer understand of reserve policy. It has been identified that, probabilistic approach is the best suited for determining generation adequacy in terms of economic and reliability point of view. Different type of reserve is allocated at different level of frequency control level. So, technical specification and timing for frequency control level of different system operator have been discussed widely. A comparison of frequency control framework between European and US is also presented. To ensure reliability and stability, it is recommended to adopt special protection scheme alongside new technologies-WAMS, SmartGrid.
