Impact of Voltage and Network Losses on Conductor Sizing and Topology of MV Networks with High Penetration of Renewable Energy Resources

Abstract

This paper discusses heuristic distribution company planning rules, which are pragmatic but challenging to implement in a planning algorithm that aims to efficiently produce close to optimum solutions. The main focus is on how voltage is handled, and how other parameters, such as the cost of network losses and the time horizon used for planning, affect voltage. This is illustrated via Greenfield horizon plans and cost breakdowns based on a typical distribution network in the south of Germany.
