IEEE PES Day Bolivia 2026: Selección de escenarios críticos para el STI considerando generación no convencional

#UCB #PES #students #webinar #Meeting #SistemasFotovoltaicos

In this technical talk, the speaker explained how the incorporation of non conventional renewable sources, such as solar and wind, introduces greater uncertainty into the operation of the Interconnected Transmission System. He presented a methodology for selecting critical scenarios based on clustering techniques and historical data analysis, which allows identifying the most challenging conditions for the network. He showed examples of how meteorological and demand data are processed to simulate contingencies, and how these simulations help operators anticipate failures and plan reserve generation. He also mentioned the use of digital twins and real time monitoring systems (PMU/SCADA) to improve response to events. The talk was highly valued by participants, as it showed a concrete application of artificial intelligence in the electrical sector.

The daily challenge corresponding to this session was the third clue of the Ruta PES Day Bolivia. The clue read: Where sugarcane grows and rice is harvested, waste is not trash: it is the food of a humble but powerful energy. This is the energy born from life that ends its cycle. Participants had to interpret that this clue referred to biomass, especially agricultural residues such as sugarcane bagasse and rice husks. The educational purpose was for participants to investigate the potential of biomass in Bolivia, both for electricity generation and heat production, and how this renewable source can provide inertia to the electrical system, unlike solar and wind. The competition consisted of participants identifying the most promising specific type of biomass in Bolivia and explaining how it could be integrated into the STI. Points were assigned based on order of arrival and quality of the response. This challenge encouraged a comprehensive view of renewable energies beyond solar and wind.

The attendance form was shared at the end. The creative question was: How could clustering techniques be used to identify the most critical zones of the STI under high wind energy penetration? Propose a simple method based on the concepts presented. This question sought for participants to apply the scenario selection methodology to a real case, demonstrating understanding of data analysis and network stability concepts.
