Energy Systems The increasingly intense use of technology

Energy Systems The increasingly intense use of technology, in applications such as smart homes, electric vehicles, and a legion of sensors of various types connected to the network, tends to reflect a vertiginous increase in the energy demand. At the same time, the concern with sustainability and environmental preservation leads to research for solutions that allow greater operational and energy efficiency through the use of distributed and renewable energy sources.

CPQD works in the development of technologies, methodologies and algorithms applied to energy systems, intending to expand the capacity, reliability, availability, and quality of electricity supply.

It develops innumerable R+D+i projects covering topics such as:
Batteries and charging and traction systems for electric vehicles

Evaluation of the performance of components for electrical mobility (electric vehicle, electrolier, electrical infrastructure, etc.).

Impact assessment of electric vehicles, distributed generation, and advanced measurement infrastructure in the distribution network.

development oF advanced batteries for use in distributed generation

Development of methodologies for improvements in real-time operations, planning, and maintenance of distribution systems.

The developments are subdivided into technological components that cover the areas of energy storage, advanced measurement, advanced automation, methodologies and algorithms, energy conversion, architecture and topology of energy systems, compliance, and regulation. The set of skills guidelines allows CPQD to carry out research, development, and innovation projects covering topics such as electric mobility, renewable sources, distributed generation and planning, maintenance, and real-time operating systems.
