FAQS about Brazil Sao Paulo Energy Storage Frequency Regulation Project
When will the energy storage initiative start in Brazil?
In April 2016, the Brazilian National Regulatory Authority (“ ANEEL ”) published the first draft of a three-year energy storage initiative in the context of its R&D programme for technological innovation in the power sector, which was launched in 2012. The initiative is expected to launch this year and project selection will be concluded in 2017.
How will energy storage regulation shape Brazil's energy future?
By advancing energy storage regulation, the agency seeks to enhance system efficiency, accommodate renewable energy growth, and empower stakeholders across the energy sector. ANEEL opens the second phase of Public Consultation on energy storage regulation to shape Brazil's energy future.
Should Brazil invest in energy storage?
Brazil's energy storage sector must attract R47 billion ($7 billion) in investments by 2030, according to the Brazilian Energy Storage Solutions Association (Absae). Stakeholders are in the process of creating a regulatory framework for energy storage.
Is energy storage a solution to Brazil's growing renewables capacity?
ANEEL's announcement is timely and shows an interest in pushing energy storage to be considered as a solution to Brazil's growing renewables capacity and urgent need to fill the transmission infrastructure gap.
What are the challenges for energy storage in Brazil?
Another challenge for energy storage in Brazil will be access to capital. Given the current unfavourable economic conditions, it is not clear how long it will take for energy storage to benefit from large-scale investments. 5.
What is the panorama of storage in Brazil?
The launch of the Panorama of Storage in Brazil marked a breakthrough in technical discussions and symbolized the beginning of a new era for the Brazilian electricity sector. With its eyes on the regulatory framework, the storage market has the potential to be one of the great drivers of the national energy transition.

FAQS about High frequency wind power base station
Does a wind farm-side MMC station have a high-frequency oscillation mechanism?
This paper investigates the high-frequency oscillation mechanism of wind farm-side MMC station during no-load charging process. First, the harmonic state space (HSS) model of a wind farm-side MMC station is established. In addition to the leakage inductance, the stray capacitance is considered in the converter transformer model.
Does stray capacitance affect high-frequency oscillation of wind farm-side MMC station?
Apart from the time delay of MMC, the stray capacitance of converter transformer makes a significant contribution to the high-frequency oscillation. This paper investigates the high-frequency oscillation mechanism of wind farm-side MMC station during no-load charging process.
What is 2 kHz high-frequency oscillation in wind farm-side MMC-HVDC project?
A new 2 kHz high-frequency oscillation has occurred in the wind farm-side MMC station of Rudong wind farm integrated MMC-HVDC project of China during no-load charging process. The mechanism of this high-frequency oscillation is different to previous ones.
Why is high-frequency oscillation threatening the stability of MMC-HVDC system?
High-frequency oscillation is one of the critical issues threatening the stability of modular multilevel converter (MMC) based high-voltage direct current (HVDC) system. A new 2 kHz high-frequency oscillation has occurred in the wind farm-side MMC station of Rudong wind farm integrated MMC-HVDC project of China during no-load charging process.
Why do wind farm-side MMC stations oscillate during no-load charging process?
The harmonic interactions of MMC and converter transformer lead to the high-frequency oscillation of wind farm-side MMC station during no-load charging process. 2. Different from PQ and DC voltage controlled MMCs, the outer control loop, i.e., AC voltage control, has great influence on the high-frequency characteristics of the wind farm-side MMC.
Does AC voltage control affect high-frequency oscillation in wind farm-side MMCs?
2. Different from PQ and DC voltage controlled MMCs, the outer control loop, i.e., AC voltage control, has great influence on the high-frequency characteristics of the wind farm-side MMC. In this case, the dynamics of AC voltage control cannot be ignored in the high-frequency oscillation analysis.
