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

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.
