Integration of Renewable Energy Sources in future power systems: The role of storage

摘要: Integrating a high share of electricity from non-dispatchable Renewable Energy Sources in power supply system is challenging task. One option considered many studies dealing with prospective systems the installation storage devices to balance fluctuations production. However, it not yet clear how soon will be needed and integration process depends on different parameters. Using long-term solar wind energy production data series, we present modelling approach investigate influence size efficiency pathway towards 100% RES scenario. Applying our for Germany, found that up 50% overall demand can met by an optimum combination resources without both curtailment if remaining provided sufficiently flexible plants. Our findings show further small, but highly efficient already beneficial integration, while seasonal are only when more than 80% energy. results imply compromise between additional generation capacities required.
