4. Improving Concentrating Solar Power Plant Performance through Steam Turbine Flexibility
Abstract : The amount of incoming solar energy to earth is greater than any other source. Among existing technologies to harness solar energy there is concentrating solar power (CSP). One advantage of CSP is that is dispatchable, meaning that it can provide power even when the sun is not shining. READ MORE
