Design and implementation of a transistorized bi-controlled based utility-connected battery charger for underdeveloped nations

This paper presents a transistorized bi-controlled based utility-connected battery charger to address the problem of erratic public power supply in underdeveloped nations. In this study, a utility battery charger was built by the integration of grid power supply, line frequency transformer, power electronic switches, alternating current-direct current bridge converter, regulator, and resistor-inductor-capacitor. The excess-voltage protection and battery monitoring were obtained by the bi-controlled technique. In contrast to other charging systems in underdeveloped nations, the proposed system is very simple, rugged, reliable and cheap to maintain due to simplicity and un-programmed nature of the system. The results showed that the proposed system is craggy and robust to resist voltage stress, highly reliable and relatively free from leakage currents due to the presence of a double controlled scheme using a common point of action and a line frequency transformer. In addition, the system can be used to charge batteries ranging from 50μA and above. The system can be utilized in communication companies, electric vehicles, drilling machines

Internet of Things (IoT) Cloud Based Model for Low Cost Demand Side Management Infrastructure

This paper presents a model for low cost demand side management infrastructure using cloud-based technology and internet of things to facilitate the implementation of smart grid in Nigeria. The electricity market has experienced a rapid increase in demand attributed to unprecedented growth in human population, urbanization, and industrialization. Accordingly, utilities are faced with the challenge of meeting daily energy demand. Research has shown that 45% of electricity generated are wasted or cannot be accounted for. Energy management is thus a major issue affecting the power sector of Nigeria. Efficient utilization of energy is therefore crucial for sustainable development both from an economic and ecological perspective. The proposed Smart, Low Cost and IoT-enabled power distribution board can be adopted and implemented as part of energy conservation measures to reduce energy demand in domestic building and mitigate the energy crisis in the country. With the IoT based smart board energy management, users can get personalized recommendation of actions for energy conservation and load shifting, and have control over the energy use and the billing system

Design Analysis of Microcontroler Based Automatic Power Management in Photovoltaic Systems

This work considered the design analysis of an energy management system to control the state of battery discharge of a solar power system without any form of load discrimination, thus preventing a sudden system shut down. The state of discharge of the storage battery is monitored by the voltage level sensor. In particular, four voltage levels were used in this work namely: 11.5V (for less critical), 11.0V, 10.5V and 10.0V (for most critical load). The outputs of the sensors are then connected to a microcontroller which is programmed to isolate the loads in the order of priority. Tests result showed that at different voltage levels, specific load was disconnected from the desired voltage thus, stored energy was efficiently conserved. Accordingly, this prototype design ensures efficient energy management in photovoltaic systems
