“…The EAR is a value that reflects the reservoir levels and how much energy they can still produce. The ENA and ERA datasets have been used in several studies, such as 42 and 43 . The absence of metadata makes it unclear which attributes from the original dataset are utilised.…”

Improvements in modelling energy systems of populous emerging economies are highly decisive for a successful global energy transition. The models used–increasingly open source–still need more appropriate open data. As an illustrative example, we take the Brazilian energy system, which has great potential for renewable energy resources but still relies heavily on fossil fuels. We provide a comprehensive open dataset for scenario analyses, which can be directly used with the popular open energy system model PyPSA and other modelling frameworks. It includes three categories: (1) time series data of variable renewable potentials, electricity load profiles, inflows for the hydropower plants, and cross-border electricity exchanges; (2) geospatial data on the administrative division of the Brazilian federal states; (3) tabular data, which contains power plant data with installed and planned generation capacities, aggregated grid network topology, biomass thermal plant potential, as well as scenarios of energy demand. Our dataset could enable further global or country-specific energy system studies based on open data relevant to decarbonizing Brazil’s energy system.

“…Meanwhile, it is reported in [27] that wind power penetration causes critical instabilities in power systems, different to the corresponding solar PV penetration. Recent studies that discuss the impact of high wind penetration in power systems can be found in [28][29][30][31][32] and that of solar PV in [33][34][35][36]. The RES possesses some characteristics which differ from conventional generation systems.…”

“…However, a better understanding of ramp characteristics in power systems could be achieved by studying both load and net load [69]. Additionally, different renewable sources present different characteristics of ramping in net loads [77] and a large amount of flexibility is required by the power system to reduce the balance or mismatch in the power system [32].…”

A Review of Improvements in Power System Flexibility: Implementation, Operation and Economics

et al. 2022

This study presents a literature review on the concept of power system flexibility in terms of its definition, indices, algorithms, implementation, economic impacts, operational impacts, and security. Although there are tremendous reviews on this subject in the literature, each paper discusses specific aspects of flexibility. Moreover, the literature is devoid of a comprehensive review of the latest improvements in terms of implementation, operation, and economics, which are addressed by the collections presented in this study. This paper, therefore, surveys some improvements that have been made in recent decades. Furthermore, we highlight the impact of the high penetration of renewable energy and energy storage systems towards enhancing the improvement of power system flexibility.

“…However, the important drawbacks associated with renewable energy systems are their inability to guarantee reliability and their spare nature [1]. Nowadays, it is well-known that the renewable energy industry is accelerating quickly and intensively rising concerns about natural resources exhaustion and climate change [11][12][13][14][15][16][17][18][19][20]. The renewable energy is seen by many researchers as part of the appropriate response to these concerns.…”

We discussed the technical challenges and power system frequency fluctuations due to high wind power penetration. The simulation analyses using a multi-machine power system model using PSCAD/EMTDC have been performed to investigate the performance of the power system frequency with the increased wind power penetration using real wind speed data. The real wind data was measured in Hokkaido Island, Japan. It was observed the power system frequency is fluctuating, and the thermal governor can minimize power system frequency more than the hydro governor. The frequency deviations are maintained within  0.24 [Hz] for thermal governor model and from 49.60 Hz to 50.50 Hz for both hydro governor model. It was also found that, the wind farm output voltage, the wind farm output power and the SG output power was also fluctuating for both thermal and hydro governor model. Comparing with the hydro governor, the thermal governor can maintain up to certain capacity.
