Smartgrids research including the renewable energy integration focuses on the design, application, evaluation, and optimization of distributed generation at low voltage level. We develop micro/nanogrids system with AC and DC 230-300 voltage output, it called dual power since 2018. Our products research is DC-DC Converter for residential (DCON) with capacity 3000 Watt, and smart-socket. Moreover, the VPP (Virtual Power Plant), the aggregation of solar pv and battery is still developed.
