Location and time domain analysis of DER in distribution load flow

The Distribution network (DN) consists of overhead & underground lines, regulators, switches and ZIP loads. The operation of Distribution network is more complex due to the presence of non-linear components. The integration of solar PV is encouraged at the load terminals to meet the increase in load demand and to improve the reliability. This paper describes the sensitivity index based methodology to locate the solar PV in the Distribution Network. To balance the continuously varying source and load, hybrid solar PV with battery is integrated, in such a way the battery charging and discharging schedule is optimised based on the availability of power. This paper also addresses the load flow analysis of the network in time domain with solar PV and battery units on IEEE 37 node test feeder.
