Siestart, a new combination of electrical energy storage and gas turbines Sven Stoye I Head of Engineering Unrestricted Siemens AG Österreich 2017 siemens.at/future-of-energy
Current challenges in the grid Higher utilization of renewables and less rotational inertia from conventional power generation units Stability of the grid and secure supply of power Higher flexibility and shorter reaction times requirements to the producers Page 2
Power producers have to broaden their capabilities ensure grid stability as the power system operation is under threat Conventional power plants (heavy duty as well as industrial scale) need: Accelerated load ramping for fast compensation of unbalances in the grid Spinning reserve as additional power reserve to stabilize the grid Islanding and off-grid services (especially for industrial power plants) Black start capability in the case of a grid failure Page 3
