Abstract

Abstract:

As a typical complex system， a new power system energy is of severe power and energy imbalances resulting from the strong uncertainty of sources and demands. The balances are challenged by the basic alteration of electric energy and power balance logic. To make a new balance between coordinated and interactive sources， networks， loads and storage devices， a hierarchical autonomous power balance model with energy autonomous units is constructed. The hierarchical structure can simplify complex systems， and energy autonomous units have self-dispatching and self-balancing capacities. The units whose forms vary with different electricity market models provide effective paths for multiple resources to participate in the power market. In software paradigm theory， an energy autonomous unit is of an architecture that can integrate multiple elements， an adaptive operation mechanism， and a life-cycle evolution mechanism. Additionally， the construction methodology of software-defined energy autonomous units based on software-hardware decoupling is proposed. Finally， the key technologies applied in the units are discussed and looked forward.

Key words: new power system, new energy, source-grid-load-storage, power balance, complex system, software-defined, energy autonomous unit, electricity market
