Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

Flexibility with Renewable energy penetration

AbstractWith increased renewable energy penetration, flexibility of the energy systems becomes more important for dynamic balancing of supplies and demands. This lecture focuses on the challenges and opportunities associated with energy transitions, for example, spatial and temporal characterization of energy demand and renewable resources for urban district, smart intervention with the new technologies for consumers into prosumers, and integration of renewable energy with energy storage. We argue that the renewable industry has reached the tipping point of competitive costs. We call for accelerating and promoting market-based distributed energy technologies, energy storage, and smart integration of prosumers to respond energy transition. Dynamics of energy systems with integrated energy storage and interative prosumer participation become more important in the future.
