As my Final year project I am trying to solve the problem of Voltage Unbalance in a LV that arises because of small Scale PV and one of the solutions I am proposing involves DSTATCOM and another is DG(Distributed Generation) or ESS(Energy Storage System - Large Batteries) and would love some help in calculating the cost for all of these.
The client for my final year project, a distributor in Victoria, Australia is going to give me smart meter data from 8-200 customers and the client would like to know the size and cost of an ESS to get Voltage unbalance in an acceptable range. Would really appreciate some help.
