Development of a secure, economic and environmentally-friendly modern power system

The composition of used energy sources is changing due to the limited resource and environmental pollution of the conventional fossil fuels. Consequently, the styles of electricity generation are varying. Recently many renewable energy based generation units, such as wind farms, and distributed generation (DG) units including some combined heat and power (CHP) units are being integrated into power systems. The power system is becoming a mixed pattern, consisting of conventional, renewable and energy conversion/storage units. The changes bring many challenges to the traditional power systems based on centralised power plants. It is necessary to appropriately handle these challenges in order to increase renewable energy share and provide reliable power supply. Therefore, developing new concepts and technologies becomes an urgent demand for creating an economic, renewable and environmentally sustainable energy system.

The proposal focuses on the necessary developments for a future power system, such as the foreseeable Danish power system in 10-20 years, with a strategic vision, by systematically developing and integrating new concepts, algorithms and approaches to establish a secure, economic, and environmentally-friendly modern power system which has a mixed pattern of generation units, consisting of renewable, energy conversion/storage units, and conventional units. Six interconnected Working Tasks are proposed to deal with system structural security; economic benefit exploitation; stably operation and control; prevention of cascade failure and blackout; intelligent utilization of various generation units; and an interactive energy system consisting of power grid and green transportation systems, such as plug-in hybrid, electric and fuel cell vehicles, with energy conversion/storage units to realize cost effective interdisciplinary applications.
