This paper studies a nonlinear predictive energy management strategy for a residential building with a rooftop photovoltaic (PV) system and second-life lithium-ion battery energy storage. A key novelty of this manuscript is closing the gap between building energy management formulations, advanced load forecasting techniques, and nonlinear battery/PV models. Additionally, we focus on the fundame...

This paper proposes a novel high-efficiency isolated three-port bidirectional DC/DC device for photovoltaic (PV) systems. The device contains a high step-up converter for PV modules to supply power to the DC bus, and a bidirectional charge/discharge control circuit for the battery with an improved boost-flyback converter. When the PV modules supply sufficient energy, their output can be stepped...

The electricity generations of photo voltaic (PV) panels are strongly related with insolation and temperature. The insolation and temperature are not stable, since the electricity generations of the PV panels are not stable. In PV systems, insolation and temperature continuous vary. Therefore, the maximum power point tracking (MPPT) techniques are used to give the highest power to the loads/bat...

This paper presents an alternative method to reduce the monthly electricity bill at Centre of Excellence for Renewable Energy (CERE) which is by installing a stand-alone photovoltaic (PV) system. In the stand-alone PV system, apart from the PV module and loads, other components in the system such as battery, charge controller, inverter and protection device are categorized under Balance of Syst...

High PV utilization ratios in buildings, i.e. the consumption of most of the PV energy within the building premises, can reduce the energy losses in distribution networks, and mitigate overvoltages and transformer overloadings. For this reason, some countries have adopted, or are discussing, regulatory instruments to motivate local utilization of PV energy. In this paper, we investigate the pot...

Grid energy storage system for PV Applications is connected with three different power sources i.e. PV Array, Battery and the Grid. It is advisable to have Isolation between these three different sources to provide safety for the equipment. The configuration proposed in this paper provides the complete isolation between the three sources. A Power Balancing Control (PBC) for this configuration i...

The main concept of the new converter is to use a Single stage three phase grid ties solar PV converter to perform dc/dc and dc/ac operations. This converter solution is appealing for PVbattery applications, because it minimizes the number of conversion stages, improving efficiency and reducing cost, weight and volume. This converter solution is appealing for PV-battery application, because it ...
