The use of photovoltaics with battery energy storage systems is popular because of the benefits it provides for household set-up as it helps with savings in electricity costs. In this dissertation, work is carried out for additional savings using energy storage systems and PV in residential set-ups and community-scale systems. The tariff which is taken is the time of use in which the rates varied between peak period and off-peak period. Hence, shifting the loading from the grid during the peak period to the off-peak period significantly reduces the electricity cost. The novel method which is the inclusion of time of use tariff with an algorithm that decides the power flow from the different components of the system like the grid, battery, and load is described in this dissertation. Additionally, the results of 1 household payback period of the initial outlay spent on PV-battery setup is compared with 10 households in community scale set-up which shows the significant savings and reduction in a payback period for the set-up. The work in this book is a complete review of the use of energy storage systems in distribution systems.
