Influence of Distributed Generation from Renewable Energy Sources on Distribution Network Hosting Capacity

The influence of distributed generation (DG) from renewable energy sources on the distribution network (DN) hosting capacity was analyzed in this paper. The analysis was conducted on the simulation model which represents a real DN with the DG consisting of medium size biogas combined heat & power (CHP) and small size household photovoltaic (PV) systems. Main goal of this paper was to analyze how the different voltage regulation methods and network topology manipulations like the integration of a new substation near the DG and adding new power lines affects the DN hosting capacity for the DG. Power flow simulations of different cases in this paper were analyzed by monitoring the voltage or current limitation levels of the elements into the network. Effect of the amount of power injected by the DG into the network on power losses was also studied.
