Control of the Connection of Renewable Sources into Network

A Point of Common Coupling Interface (PCCI) is used for a simple, standardized connection of micro and small generation of electricity from renewable energy sources in network. It enables monitoring of energy generation and ensures safe disconnection from network. All types of electric energy from renewable sources or energy from photovoltaics, wind power stations, cogeneration, hydropower stations as well as “classical” small power stations can be connected.


For whom:

  • For designers of small power stations, investors in small power stations, electric utilities, owners, operators of business buildings, etc.

    • Your benefits:
  • For all types of micro and small generation of electricity

  • Completely safe and supervised energy generation

  • Remote monitoring and control

  • Simple communication with the control centre

  • Simple connection of small power stations to public distribution network

  • Connection of generation and consumption in the same cabinet (lower costs, more transparent control)

  • Provision of uninterrupted power supply (UPS) related with renewable energy sources (RES) and energy storage reservoirs

  • Possibility of monitoring electric energy quality

  • Possibility of compensation control

  • Various control functions available (voltage, frequency, island operation, etc.) or optional combination

  • Possibility of adding a small compensation device

  • A cabinet is compliant with the requirements of electric utilities and with the regulations on connection of small power stations.

    • Constituent parts:
  • Energy meters

  • Communication units

  • Circuit breakers and contactors

  • Fuses, fuse disconnectors

  • Surge protective devices

  • Control relays

  • Current measuring transformers

  • Additional equipment and accessory
