Stable renewable power supply in microgrids

(BSC/Pfisterer) The new CrossPower system allows robust and scalable microgrids to be created from renewable energies anywhere in the world. Compared to conventional diesel generators, fuel savings of up to 50 percent can be achieved. An intelligent control system effectively balances power generation and consumption while high-performance battery storage ensures constant grid stability.

Consumers with different priorities

Consumers can be prioritised as required. This means that medical facilities, fridges or an IT system are guaranteed 100 % power supply even in the case of an overload. Accommodation, TVs, etc. on the other hand have a lower priority. If there is not enough energy available they will be switched off.

Can be transported as required

The entire CrossPower system can be housed in a standard container, if necessary. The pluggable terminals from PFISTERER allow fast assembly on-site without qualified personnel. Even when operating, the system is fully autonomous and can be maintained remotely if required.

Solar panels, wind turbines, modern diesel generators: these are the different types of CrossPower energy sources. Due to its intelligent power management system, reliable and weather-independent use can be made of renewable energy to generate electricity in remote areas, in conflict zones or refugee camps. Modern lithium-ion batteries and modern diesel generators ensure a stable supply of power. Combining photovoltaic arrays and wind power plants with conventional diesel generators leads to a significant reduction in operating costs and fossil fuel consumption.

Green energy comes first » Scalable for outputs from 25 kW to 1.000 kW » Flexible power management for all types of energy sources » Powerful batteries ensure high network stability around the clock » The power management system prioritises renewable energy sour ces » Consumers can be prioritised » Safe remote monitoring possible

The main task of the control software is to guarantee grid stability around the clock with optimum energy efficiency. The system selects the renewable energy source independently. As soon as there is an oversupply of energy, the battery is charged. If there is not enough power being generated, for example when there is no wind or it is raining, the controller utilises the batteries to their minimum capacity, before falling back on diesel generators. Thus, the system achieves an efficiency rate of 90 %. A 25 kW version of CrossPower: independent power from renewable energies Photo: Pfisterer
