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.
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:
Solar power plants may be remotely controlled.
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:
Photovoltaic, battery and power-to-gas merge.
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.
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:
Offshore wind farms can also provide reserves.
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:
