一种构建高效微电网的微微网系统
摘要：
本发明属于新能源电力技术领域，具体涉及一种构建高效微电网的微微网系统。本发明提出的技术方案，由多个电力调控与变流系统、发电单元、蓄电单元及用电负载组合，将每个电力调控与变流系统与同级发电单元、蓄电单元及用电负载相连，再由多个电力调控与变流系统逐级相连组成微微网系统，即可独立运行又可受控共享。将微微网系统作为微电网及大电网的发电、供电、蓄电一体化节点系统接入微电网或大电网，多个发电单元可以自发自用，达到供充分自治，并且可以互连组网，受控并网及共享，实现了发电用电整体电力合理调控，优化了多种电力的调节与调配，在优先利用新能源电力的同时实现受控并网和子系统之间的资源共享，由于真正实现了分布式发电与供电更加有效地化解了系统风险，大大提高了微电网系统的可靠性和安全性。
摘要（英）：

The invention belongs to the technical field of new energy electric power, and specifically relates to a piconet system for constructing an efficient micro grid. According to the technical scheme provided by the invention, a plurality of electric power control and conversion systems, power generation units, electric power storage units and power utilization loads are combined, each power control and conversion system is connected with the power generation unit, the electric power storage unit and the power utilization load at the same stage, and then the plurality of electric power control and conversion systems are connected stage by stage to form the piconet system which can run independently and can be shared under control. The piconet system is accessed into a micro grid or a large grid as a node system integrating functions of power generation, power supply and electric power storage for the micro grid or the large grid, a plurality of power generation units can be self-sufficient to achieve full autonomy of power generation and power supply, and can be networked through interconnection and can be grid-connected and shared under control. Reasonable overall electric power control on power generation and utilization is realized, adjustment and allocation on various electric power are optimized, and controlled grid connection and resource sharing among subsystems are realized while new energy electric power is utilized preferentially. As distributed power generation and power supply is truly realized and system risks are defused effectively, reliability and safety of a micro grid system are greatly improved.
