Maximise the value of renewable energy sources
In working towards Wärtsilä Energy’s goal of a 100% renewable energy future, energy storage is becoming increasingly critical to help strengthen the reliability and flexibility of the grid and to integrate more renewable power into the system.
The combination of renewables and storage makes it possible to produce smooth power output when weather conditions are less than ideal, minimising impacts on grid stability. For example, fast-acting energy storage operating in concert with the solar system can control power quality by calibrating battery charging and energy exports to the grid. Consequently, storage mitigates the need for large-scale solar to curtail output as clouds come and go.
Wärtsilä’s Renewables+ hybrid solution delivers firmed, 24-hour capable and fully dispatchable solar energy to the electrical grid in optimised ways
Globally, the rapidly growing installed base of utility scale photovoltaic (PV) plants has led to the decreasing tariffs and incentive schemes offered. This has created profitability pressures in highly competitive business environment for the investors. Additionally, ever growing share of intermittent renewable power generation feeding electricity to the grid has created grid stability challenges for the utilities and further requirements for smooth grid integration and operation is demanded from the power plant owners.
The GEMS Power Plant Controller oversees and controls the Renewables+ storage hybrid plant functions. The solution is capable of dispatching or storing real power and absorbing or injecting reactive power in optimised ways via the GEMS platform.
The solution’s application list is complete and flexible for future changes in market structures and tariffs. Applications can be stacked (i.e., perform simultaneously), prioritised and scaled according to market and project requirements.
