Switched Intelligent Grid Networking Systems (SIGNS) is the result of research, analysis and development of an alternative process for controlling end-user electrical power quality, as well as transients on the incoming electricity supply grid. In the past power quality issues associated with the grid network were usually generated by the connected loads. This has changed in today’s grid system with embedded intermittent renewable energy being included on the energy profile. The research demonstrated that it is possible to control end-user electrical power quality through the addition of battery storage at the user end of the grid and a switching device, forming an intelligent buffer between the electrical grid supply and the load. The function of the device is to select the most appropriate energy source to effectively absorb a proportion of any surges and transients, whilst offering a path for augmented alternative energy.
