RENEWABLE ENERGIES 2.0 Through its PowerTech technology, Knorr Bremse is at the forefront of designing energy concepts for the future. Power s are an important link between energy sources, consumers and applications. They optimize power that is generated by individual power sources such as windparks. Power s also help optimize the power grid by converting excess energy during peak loads to stored energy and then converting this stored energy back to the grid during non-peak times. PowerTech also has the expertise to optimizes grid power by feeding in reactive current for power factor optimization and low voltage ride through. FULL POWER FOR THE GRID Todays energy grids increasingly balance various energy sources and loads. This could include wind, solar, hydropower and conventional energy sources combined with concepts such as batteries or power-to-gas. With the aid of grid compensation systems for large hydrolysis systems, for instance, or simply for large consumers of supplied power, the load on the grid is significantly reduced by minimizing the reactive currents produced there that cannot be utilized. PowerTech is working intensively on the development of these systems for large public grids but also for smaller isolated systems with black start capabilities (microgrids). AREAS OF APPLICATION Renewable energy sources Industry and production Intelligent power generation: Inverter, grid support, Intelligent consumption: Optimized energy supply, grid compensation Energy applications Energy solutions Residential areas & isolated networks Micro-grids & UPS Solar & wind energy Power-to-gas Battery Compressed air Flywheel
EFFICIENT ENERGY CONVERSION WITH GRID STABILITY: Cutting-edge technology from energy generation to NEW STANDARD FOR OPTIMIZED ENERGY SUPPLY Knorr-Bremse PowerTech s for energy generation and convert energy from generators/motors or renewable energy sources into the needed form to supply the grid or be stored. That allows PowerTech frequency s to supply and connect energy generation and systems in the optimum way and provide grid stability for the relevant application. They integrate the generated energy and allow it to be fed to the grid or stored for later use. This ensures efficient and environmentally friendly consumption.
