Regulatory frameworks, environmental concerns, and the growing economic viability of alternative energy sources drive the increased use of distributed generation in the Brazilian electrical system and bring challenges in the areas of energy processing, conditioning, and storage in connection with the energy distribution network.

In this scenario, customers wishing to invest in these modals can count on Lactec researchers for:

  • Computational modeling of sources for system planning and operation;
  • Integration of renewable sources in special situations, such as electric vehicle charging, management on the demand side and energy storage;
  • Operation of distribution networks in isolated mode through microgrids;
  • Analysis of impacts of connecting alternative energy sources in low and medium voltage distribution networks;
  • Definition of standards adapted to the Brazilian scenario;
  • Introduction of national technology in segments dominated by international companies;
  • Formation of partnerships with institutions outside the country; and
  • Technological advance in segments poorly exploited by the concessionaires.

Lactec maintains contact with researchers from all over the world to guarantee the development of projects and solutions to take advantage of the best energy potential of these sources and present to its clients solutions and studies that meet the needs of each market.

HYDROELECTRIC POWER

With the great availability of Brazilian hydroelectric power, most of the energy that comes to the country’s homes comes from hydroelectric plants. In this type of generation, electric energy is the result of the conversion of the potential gravitational energy of the water flow. In addition to the so-called HPPs, which are the large plants, the vast expansion of the SHPs, the small hydroelectric plants, can be observed. For both, Lactec offers specialized technical services and conducts R&D projects in the areas of hydraulics, environment, electricity, mechanics, construction, electronics, and information technology. Lactec has wide recognition in this sector, having renowned works in its portfolio, such as the Itaipu (PR), Belo Monte (PA), Salto Caxias (PR), and Salto Segredo (PR) HPPs.

PHOTOVOLTAIC SOLAR ENERGY

fonte solar Photovoltaic solar energy is that which, through a solar cell, uses light to generate electrical energy. With the growth of the concept of distributed generation, this source started to be used by both concessionaires and independent generators, and, for this reason, research in this sector is essential for the discovery of more efficient forms of generation and the balance of the energy distribution system as a whole.

HELIOTHERMAL ENERGY

ConcentradoresHelio-thermal energy or concentrating solar thermal power is a generation technology that transforms direct solar irradiation into thermal energy and subsequently into electrical energy. It uses mirrors of varying configurations to concentrate the sun’s rays and heat gases or working fluids. Researches in this sector were stimulated in Brazil, at the end of 2015, through the Strategic Call nº 19 of the National Electric Energy Agency, Aneel. Due to its potential to generate dispatchable energy, several concessionaires seek Lactec to conduct their research.

THERMAL POWER 

termicaThermal power plants are plants that generate electricity by burning components such as natural gas, coal, biomass or fuel oils. With the recent demands for energy availability, thermoelectric plants started to present the necessity of research and development projects. Lactec is ready to supply plant instrumentation (electric, mechanical and hydraulic); dispatch optimization; energy efficiency; energy quality; besides the development of environmental solutions and reduction of atmospheric emissions.

EOLIC ENERGY

eólicaEolic energy is that which is used from the wind for the generation of electric energy. It involves research in the areas of mechanics, electronics, electrics, civil engineering, and environment. With optimistic forecasts of growth in the share of this energy source in the Brazilian energy matrix, research is essential for safe investments for energy concessionaires.

BIOGAS AND BIOMASS ENERGY

biomassaThe generation of electric energy through biogas and biomass is the result of the biological degradation of organic waste, whether of animal or vegetable origin. Lactec can assist in generating this energy through a series of R&D projects, especially in the development of biodigesters for the treatment of residual agricultural and pig farming biomass. This guarantees the improvement of rural sanitation, in addition to potentializing the generation of decentralized, renewable, and low environmental impact energy.

POWER STORAGE

banco de baterias armazenamento solarThe energy storage or power storage system is composed of energy accumulators, power systems, monitoring, and control system and connection to the utility system (Scada). It allows the utility to store energy safely, ensuring availability, and keeping the power steady. Through research and project development, it is possible to elaborate a consistent business plan for system implementation; evaluate the technical and economic viability of energy storage, considering different scenarios, including eventual regulatory and incentive changes; in addition to developing the system management and control software, performing its operation and monitoring.
