Stable Power Supply with Sun and Wind

An increasing energy supply from mercurial regenerative sources changes the need for system services and requires greater flexibility in energy supply. WAGO supports grid operators who intelligently link and control renewable power.

The share of renewable power is increasing steadily and rapidly internationally. The fluctuating power from photovoltaics and wind, however, has disadvantages for grid management. The unstable supply makes it more difficult to predict generation output and ensure grid stability. But there are solutions that relieve the load on the grid.

Feed-In Management: Targeted Throttle Down of Sun and Wind

To ensure system security as renewable energy sources increase, grid operators can reduce the feed-in capacity of solar and wind farm systems remotely in the event of grid overload. The Renewable Energies Act stipulates the regulations depending on the plant's output. Depending on the required signal range, WAGO assembles the appropriate telecontrol solution for you from more than 500 different I/O modules.

Advantages of WAGO's solution:

  • Broad product portfolio: From simple step control with or without emergency stop command to cos-ϕ or Q/U control
  • Direct coupling to the solar or wind farm's computer via OPC-XML, Soap or MODBUS RTU/TCP possible
  • Communication from the system according to custom requirements
  • Cybersecurity: PFC100/PFC200 Controllers comply with current IT security regulations for grid operators and can be hardened as described in the BDEW white paper.
  • Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade
  • Coupling the systems via IEC 60870, IEC 61850 or DNP 3.0 also possible

Solar power plants may be remotely controlled.

Virtual Power Plants: Intelligent Networking of Generation and Consumption

In virtual power plants, decentralized generators, storage systems and controllable loads, such as emergency generators or production systems, form a flexible and adjustable combination. Intelligently synchronizing these reduces loads on the power grid. WAGO Telecontrollers meet the requirements of the VHPready 4.0 communication standard, ensuring trouble-free connection of systems.

Advantages of WAGO's solution:

  • Trouble-free connection of individual systems to the virtual power plant
  • Standardization of the objects and variables of different communication protocols with VHPready
  • Communication via predefined profiles using explicitly defined data point lists
  • Definition of domain-specific determinations like the specifications for operating behavior and reaction times via VHPready – this way, plants can be controlled via timetables.
  • Cybersecurity: PFC100/PFC200 Controllers comply with current IT security regulations for grid operators and can be hardened as described in the BDEW white paper.
  • Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade

Photovoltaic, battery and power-to-gas merge.

Translator for the Grid

Thanks to the energy standards, energy generators and consumers are easier to connect to the virtual power plant, because they bring objects and variables using different communication protocols to a common denominator. WAGO Controllers already meet the requirements of the new specification.

Operating Reserve: First Aid for the Grid

An operating reserve compensates for grid fluctuations. If operators of virtual power plants or individual generators and controllable consumers supply this power to the responsible transmission grid operators, they can generate additional revenue. For operating reserves, a distinction is made between primary, secondary and minute reserves that must be supplied within seconds, five minutes and 15 minutes respectively. Due to high standards for signal diversity, cybersecurity and availability, flexible, safe and rugged controllers are essential.

Advantages of WAGO's solution:

  • Selection of more than 500 different I/O modules
  • Direct coupling to the solar or wind farm's computer via OPC-XML, Soap or MODBUS RTU/TCP possible
  • Communication from the system according to custom requirements
  • Cybersecurity: PFC100/PFC200 Controllers comply with current IT security regulations for grid operators and can be hardened as described in the BDEW white paper.
  • Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade

Offshore wind farms can also provide reserves.

Direct Marketing: Sell Green Electricity Profitably

Direct marketing means the sale of electricity from renewable energy sources to large customers or via the electricity exchange. Direct marketing distinguishes between mandatory direct marketing of new systems and optional direct marketing of existing systems. Green electricity is treated similarly to conventionally generated electricity and sold at the same market price. After the sale, the sales revenue from the electricity exchange is paid to the system operator together with a market premium to generate additional revenue. In traditional direct marketing of EEG systems, operational readiness and efficiency are captured. In addition, setpoints for the active power are specified as a staircase signal or sliding. WAGO provides the right solution for every application:

  • Selection of more than 500 different I/O modules
  • Measurement of active power via 3-phase power measurement modules
  • Measurement of performance values via existing measurement devices (e.g.,Modbus RTU/TCP/UDP, PROFIBUS)
  • Measurement of performance values via existing meters (e.g., via S0 impulse, IEC 62056-21 or SML)
  • Direct coupling via inverter protocols, solar farm controllers or wind farm computers
  • Cybersecurity: PFC100/PFC200 Controllers comply with current IT security regulations for grid operators and can be hardened as described in the BDEW white paper.
  • Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade

Instead of feed-in remuneration: Electricity sales on the open market
