Abstract

Renewable energy based micro grid planning is perfect for delivering electricity to rural areas, as an uninterruptible resource. In this paper, a DC micro grid system is designed. The system consists of several PVs and batteries which are connected to each other through a network. PV grids A and C deliver 1,904 watts of power in the micro grid system, while the battery contributes 784 watts of power. The system has a load of 730 watts. The purpose of this study is to improve the performance of micro grid with off-grid systems. The performance of the designed system is quite good because there sources of the grid A and grid C systems are sufficient to meet load demands and to charge batteries. When solar radiation is low, the battery meets load demands. To make the system more reliable, although it will increase system costs, a battery with a larger capacity can be used. The proposed system maintains the voltage at 12V with a change of only ± 10%.

Abstract

DC microgrid is a good solution for increasing demand for electricity loads and is an effective way to utilize renewable energy sources into distributed generation systems. Solar energy has intermittent properties when DC microgrids are used. In the previous research, the battery was used as an energy reserve to overcome fluctuations in the output power of photovoltaic (PV) arrays. However, the use of many batteries requires a high cost. This study aims to reduce power fluctuations on the DC bus, when the DC microgrid source from the PV array and battery is disconnected. The research method was carried out using MATLAB simulations, by designing a DC/AC coupling hybrid configuration. This configuration used two PV arrays, two multi-battery sources, and a utility network. DC microgrid settings were done separately by each converter by sending a reference signal to the converter control. In the first condition, the DC load and AC load were supplied from the PV array. In the second condition, the load was supplied from the battery. Meanwhile, in the third condition, the load was supplied from the utility network. The results showed that when using a PV array source, the DC bus voltage remained stable at 48 V, even though there was a spike at 08.00 and 15.00. Likewise, when using a battery source and utility network, the DC bus voltage was maintained at a level of 48 V. In this study, the DC microgrid was able to supply the load uninterruptedly using three conditions or modes. Therefore, the DC microgrid hybrid configuration can provide continuous electric power.

Abstract

Purpose: The output power of PV (photovoltaic) changes according to changes in the intensity of solar radiation. Therefore, the purpose of this study is to use a utility grid connected system to overcome changes in solar energy sources and loads. This is done to maintain an uninterrupted power supply to the load.Methods: In this study, we propose a grid-connected PV system with several DC-DC converters connected in parallel with several PV sources and batteries with PI control coordination. The proposed method includes two stages, namely the DC-DC converter development stage and the battery management strategy stage.Results: The study results show that within 0 seconds to 0.45 seconds the DC bus is supplied with PV. Due to the change in PV, within 0.45 seconds to 0.65 seconds the DC bus is supplied with unit-1 battery. When there is a change in the unit-1 battery, within 0.65 seconds to 0.8 seconds the DC bus is supplied with the unit-2 battery. By using PV coordination arrangements and battery units, the microgrid can still supply power to the load even if changes occur in the PV or grid.Novelty: The novelty in this study is a new microgrid configuration to increase the demand for electrical loads. The new configuration uses multi-PV and multi-battery. Multi-PV is used to supply the load and is stored in the multi-battery, while multi-battery is used at night and if there is a disturbance at the PV output.
