System supplier for renewable energies

Building blocks for a renewable energy system

In an energy system based on renewables, intelligent networking of flexible electricity producers and consumers and the infrastructure is becoming more and more important. As a supplier of renewable energy systems, ENERCON already has an extensive range of products and services to meet your needs as a customer.

350 kW rapid charging solution

The large-scale installation of a high-performance quick charging infrastructure is an essential prerequisite for a successful start to e-mobility. Charging e-vehicle batteries in just a few minutes plays a decisive role in improving the operating radius and thus the acceptance of environmentally-friendly e-vehicles.

ENERCON is developing an innovative rapid charging solution for e-vehicles based on its inverter technology. It meets the upcoming HPC2 rapid charging standard with charging capacities of up to 350 KW (DC) and has many grid-friendly characteristics that are also features of ENERCON wind energy converters. These include the highly dynamic provision of reactive power to maintain grid stability.

ENERCON pursues two objectives with the rapid charging solution: on the one hand, creation of a further sales channel for wind energy in another sector as a contribution to the changes that the transportation sector will have to undergo and on the other hand, supporting the efficient operation of charging columns for e-mobility and development of new business areas within the context of ENERCON’s system concept in which ENERCON provides solutions for more added value in relation to its core product, wind energy converters, as a systems supplier for renewable energy.

ENERCON Storage technology

Energy storage systems are key technologies in the implementation of the energy transition. As flexible consumers, they store surplus energy, which can then be made available once demand returns. With their help, the fluctuating renewables contribute to stabilising their feed-in power and reconciling generation and consumption better. That way, they guarantee grid stability and reliability of supply regardless of back-up fossil fuel power plants and fulfil their increasing responsibility for the energy system.

ENERCON is involved in various pilot projects in the field of storage technology. Our expertise lies in the provision and control of interface features for connecting storage systems to the grid. The interface features are based on ENERCON’s inverters, a core ENERCON technology that is installed in every ENERCON wind energy converter and ensures that the energy thRAat is produced is converted to a grid-compliant voltage.

Power to Gas

By converting electricity to gas (Power-to-Gas, PtG, P2G), excess energy can be stored in the natural gas network in the long term. During the PtG process, electrical energy is converted into hydrogen, a chemical energy source that can be fed into the pan-regional transmission grid, through electrolysis. Alternatively, the power being fed into the local distribution grid is also considered if the hydrogen generated is first converted into synthetic natural gas in a further step by methanation. The synthetic natural gas generated in that way can substitute for natural gas from fossil sources and thus drive the energy transition in the heating sector. If required, the gas generated can also be converted back again in combined heat and power plants.

ENERCON is involved in pilot projects on the subject of PtG. The aim of the involvement is to demonstrate that PtG plants can be integrated into the grid as controllable loads and used effectively for system stabilisation.

STATCOM

The entire power, the so-called apparent power, of a transmission grid is made up of active power and reactive power. While the electric consumers connected to the grid transform the active energy, the reactive energy is not consumed and converted into work or heat. The reactive power is merely used on the consumer side to create a magnetic field, for example for operating electric motors.

Reactive power arises if power is obtained from the power supply grid and fed into the grid again with a time delay and oscillates between the consumer and the power generator in that way. Direct electrical components such as coils and condensers can absorb energy and discharge it again after a certain time - out of phase. Due to this additional load, the grids must be sized for more power in order to also absorb the oscillating reactive power in addition to the active power provided.

If a compensation plant that generates the reactive power and absorbs it again is installed near to consumers, the grid can be relieved of the reactive power and therefore sized for less power. In grids that are relieved in that way, the apparent power corresponds to the active power and more capacity is available for electricity transmission.

ENERCON supplies so-called ENERCON STATCOM (Static Synchronous Compensator) units based on its inverter technology for expanding the feed-in power. Thanks to as-required reactive power compensation, STATCOM units ensure an even reactive power balance in the grid and thus maintain the grid voltage. Either ENERCON wind energy converters can be equipped with STATCOM features or STATCOM units can be set up separately as containers in regions where the grid should be stabilised locally with the help of regional system services.
