Abstract:
|
Grid voltage rise and thermal loading of network
components are the most remarkable barriers to allow high
number of distributed generator (DG) connections on the
medium voltage (MV) and low voltage (LV) electricity networks.
The other barriers such as grid power quality (harmonics,
voltage unbalance, flicker etc.) and network protection
mechanisms can be figured out once the maximum DG
connection capacity of the network is reached. In this paper,
additional reactive power reserve of inverter interfaced DGs is
exploited to lower the grid voltage level by means of locationadaptive
Q(U) droop function. The proposed method aims to
achieve less grid voltage violations thus more DG connection on
the electricity distribution networks can be allowed. |
