Dual Power
The Dual Power system is a new electrical system that uses AC and DC voltage as the energy sources. This system has been developed by the Tropical Renewable Energy Center (TREC), Faculty of Engineering, University of Indonesia since 2018, led by Dr. Eko Adhi Setiawan. This Dual Power system consists of two main components, an inverter or utility grid that supplies a voltage of 230 VAC and a DC-DC Converter or DCON which is a tool for converting electrical energy developed by the research team of TREC research with a voltage output of 230 VDC. This Dual Power System take the use of renewable energy sources such as solar PV, wind turbines, micro-hydro, clean energy sources such as fuel cells and batteries as shown in the image.[1]. The development of the Dual Power system aims to supply electric household electrical appliances that are more stable and efficient so that the household electrical appliances can have a longer lifetime. This system has also been tested for charging electric vehicles (e-scooters) and household electrical appliances which will be discussed in the next section. Through this concept, the integration of clean energy, batteries, internet of things, and electric vehicles can more easily be realized.
DCON (DC-DC Converter) and PLC[edit]

DCON (DC-DC Converter) is a power electronic converter that converts 48 VDC to 230 VDC. The 230 VDC voltage was chosen to make it equivalent with the voltage of the utility grid so that it can optimize the deployment of renewable energy sources, clean energy (fuel-cells), and batteries, which use the DC voltage. The output from DCON is supplied to the household appliances such as lamps, computers, televisions, electric stoves, and electric vehicles. The existence of this converter can make the power supply from the source to the load no longer going through the conversion process so that the system can be more efficient [2] . PLC Dual Power is designed to control several distributed generations by usings IoT sensors and decided priority operations during normal and fault condition.
The First Implementation Project of Dual Power[edit]
Dual Power Nanogrids, which has been operating since January 2018, is located in a residential area in Depok. This house consists of 5 kWp photovoltaic and 9.6 kWh battery as the main power sources and the utility grid as a backup power source. There is also a 2.5 kW DCON, bidirectional inverter and grid-tied inverter [3].
Second Implementation Project of Dual Power[edit]
Dual Power Nanogrids, which has been operating since 25 October 2018 for 2 years, is located at Engineering Park FTUI. This house is made using used containers so that it is more eco-friendly. This house uses 2.4 kWp solar photovoltaic, 5 kW fuel cell as its energy source, and the utility grid as a backup energy source. Additionally, there is a 2.5 kW DCON, 5kW bidirectional inverter, and 19.2 kWh battery. This Dual Power system is installed with a PLC (programmable logic controller) which serves to carry out the execution of three operating scenarios and online monitoring[4].
This container house is implemented with the 5RIPPLES concept, namely Recycle, Reuse (reusing waste containers with different functions before), Renewable (using renewable energy as a priority), Realiable (electricity produced reliably), Reduce (reducing pollution and electricity) bills), Independent (electricity does not depend on utility grid companies), People (houses play a role in providing electricity), Peace (the use of renewable energy does not cause conflicts such as oil and gas), Local (uses energy in the local area), Efficient and Sustainable[5]
