The paper presents the design of a charge controller for a standalone photovoltaic (PV) system. It comprises of a battery to store the energy for eliminating intermittency in the electricity supply, a boost converter solely operated to achieve MPPT and a bidirectional buck-boost DC-DC converter for intriguing the philosophy of charge control. The charge control algorithm envisages controlling the...
All hybrid electric systems require a strategy of energy management to share out the flow of energy between its several sources or storage devices. In this work we propose a constrained Model Predictive Controller to distribute the energy in a battery/ultracapacitor hybrid system. The studied system is used as a power supply/storage system in electric and hybrid electric vehicles and the proposed...
In this paper three topologies of interleaved boost converters efficiencies are determined by calculating the losses of the components in the converter and compared. Batteries used in REESS are protected by charge controller using PWM technique. Overcharging batteries can reduce battery life or damage them so badly they become unusable; the charge controller regulates the power flow and protects the...
A micro grid consists of several distributed generation resources and local loads, which provide the solution to supply premium power to remote or specific areas. To the design of a micro grid, it is necessary to perform computer simulation for the planning and study. Before the actual system is built, all potential responses of the system should be known and then the design can be modified to avoid...
