Design of a gsm-based remotely operated electrical energy management system

Abstract

Electrical energy is a scarce resource in most developing countries. This has prompted numerous research into ways in which commercially deployed wireless communication technologies can be used to monitor, control and manage such energy. Analysis of many of such electrical energy management systems reveal inherent complexities in their deployment and operation. This has therefore motivated the proposal of a remotely operated electrical energy management system (ROEEMS). The proposed system is designed to manage electrical energy from three different sources such as commercial grid, photovoltaic arrays, and portable generator, and give an output depending on requirements of its operator. ROEEMS has been designed to overcome some challenges in existing systems such as system complexity and security demands (as is typical of Internet and server-based systems). The proposed design allows ROEEMS to achieve a truly remote operation mode while requiring limited operator skills and a comparatively reduced cost of installation and operation.
