摘要:

新型电力系统是一个典型的复杂系统,源荷双侧的强不确定性导致电力电量时空分布极度不平衡,电力电量平衡逻辑发生了根本性变化,电力平衡面临巨大的挑战。为建立源网荷储多元协同互动的新型平衡模式,根据分层可以弱化复杂系统复杂性的理念,提出了基于能量自治单元的分层自治电力平衡模式。能量自治单元具备自调度、自平衡能力,在不同市场模式下具备不同的具体形态,将成为多元海量资源参与电力市场的有效途径。基于软件范型理论,指出能量自治单元应具备多元融合的架构模型、自适应运行机理和持续演化的生命周期,同时介绍了基于软件定义的能量自治单元软硬件解耦构建思路。最后,对能量自治单元构建的关键技术进行了讨论和展望。

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.
