Researchers conclude that clean generation technologies provide flexibility to the SEN
January 10, 2023
Using mathematical tools, Francisca Jalil and Eduardo Álvarez from ISCI studied how the joint action of CSP-TES and BESS systems, among other options, contributes to the energy system.
The reliance on fossil fuels for energy production has created an urgent need to transition to a decarbonized energy matrix. But is this possible, and are the necessary measures being taken in this process?
This question drives the work of researchers from the Complex Systems Engineering Institute (ISCI), Francisca Jalil, an expert from the Center for Energy Transition (CENTRA-UAI, Universidad Adolfo Ibáñez) and the University of Bristol, and Eduardo Álvarez, an academic at the University of Talca. Using mathematical tools, they confirm that the most likely scenario involves incorporating renewable energies into Chile’s National Electric System (SEN).
Expanding Energy Planning Tools
Long-term energy planning in Chile, and in any country, is a dynamic and multifaceted process. The mathematical tools supporting decision-making must reflect these characteristics. “In this context, this work stems from the need to expand the available analytical tools and study scenarios within Chile’s long-term energy planning process (PELP),” explains Álvarez.
The study enhances the mathematical representation of technologies that provide flexibility within the energy planning model, with a particular focus on concentrating solar power plants with thermal energy storage (CSP-TES) and battery energy storage systems (BESS). “On a technical level, the results show that CSP-TES plants are particularly effective in providing the generation flexibility required by electric systems with high penetration of renewable sources,” Jalil adds.
Meeting Emission Reduction Goals
Jalil elaborates: “In an increasingly electrified energy system, only proper planning of growth and operation will ensure emission reduction targets are met without compromising system security. Developing tools like these provides additional support for decision-makers, enabling them to send the right signals to the market to steer the system toward its goals.”
Key Findings
The study highlights the role of sustainable technologies in energy generation and their contribution to flexibility in Chile’s electric system between 2018 and 2050. “We analyze how the combined action of CSP-TES, BESS, and transmission systems can facilitate the integration of variable renewable generation technologies,” Álvarez explains.
Hydrogen Integration
Currently, the researchers are developing strategies for the mass integration of electrolytic hydrogen production and supply chains into Chile’s electric system. They are evaluating the impact of this load on system growth and operation in the medium and long term.
