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

Digital – Down to the Fingertips

PLM, ERP, MES – In the industries of the future, software technologies like these will be increasingly used to digitize and automate ordering and production processes. No business headed for smart factory technology can afford to be without them. The people at WAGO, based in Minden, Germany have realized this, too. As early as 2000, the company began to comprehensively digitize its value added chain. Today, the manufacturer of electrical interconnection and automation products not only saves on paper, it also decides when and where orders will be processed in a fully automated manner. This is especially relevant, not only when shipping in-stock items, but also when producing custom products for customers.

Savings with Spring Clamp Terminals

When the automotive company wants to reduce costs, the suppliers must also react. F.EE builds control cabinets for a number of OEMs, and the compact WAGO spring pressure connection technology facilitates the work. The company, located in the Upper Palatinate, has relied on the innovative clamping technology since the 80s.

The Trend toward Compact Power Plants

2G Energy AG exploits a number of application areas for cogeneration plants with their g-box. The compact systems are tailored to be profitable small power plants, with an electrical output range from 20 to 50 kW, for use in small hotels, industrial operations, or apartment blocks. The CHP specialists from western Münster have designed the quiet turnkey module for coupling power and heat to be particularly lean. Completely assembled DIN-rails from WAGO are used for the electronics connections.

Installation and Service Are Simpler

The times of clearly delineated machine rooms at the head of shaft systems are coming to an end in residential and commercial buildings. The structural volume allocated for modern elevators is being increasingly reduced. Spatial efficiency is everything. The technology has moved from the machine housings to the shafts, namely to those areas where there is still free space. Janzhoff Aufzüge, specialists in elevators and escalators, use the TOPJOB® S Rail-Mount Terminal Block System from WAGO for handling the dramatically increased level of data strings involved. By using the associated marking system, they have achieved additional efficiencies during installation and servicing.
