Energy Internet is studied as a promising electricity-centered energy network, which revolves around reliable framework, widely interconnected, highly intelligent and open interaction. In this paper, we propose the system structure of energy switch and the mainly function of energy switch. And then a optimization model of energy management in microgrid based on energy switch was built. The optimization...
A hybrid distributed generation system (HDGS) using a multi-input multi-output positive buck-boost converter (MIMO-PBBC) is proposed for the supply-side of the grid-connected photovoltaic (PV) generation power plant, where three PV clusters, one battery bank, and one supercapacitor module are hybridized and regulated by a centralized three-phase dc-ac inverter with their corresponding control systems...
This paper presents a new electrolytic capacitorless and single-stage controlled three-phase battery charger with electrical isolation to provide wide-range output voltage for EV applications. To achieve this, a three-phase rectifier cascaded by a current-feed isolated converter is proposed to yield DC voltage output and eliminate the bulk electrolytic capacitor installed behind the rectifier. Therefore,...
Based on the multi-sensor system, one energy-saving control method is provided to extend the working period of solar street lamp. The multi-sensor system applies infrared and sound sensors to collect and recognize the signal of man body, and then controls the switch time of lamp based on the lighting-control method, and adjusts the output power and lighting luminance dynamically. This new control...
