Abstract: |
Distributed photovoltaic generators (DPGs) have
been integrated into the medium/low voltage distribution
network widely. Due to the randomness and fluctuation of
DPG, however, the distribution and direction of power flow
are changed frequently on some days. Therefore, more
attention is needed to ensure the safe operation of the
distribution network. The installation of energy storage
systems (ESSs) can help the network to withstand the
fluctuations caused by DPG. Based on the discrete Fourier
transform method, this paper presents an ESS capacity
allocation strategy for the medium/low voltage distribution
network with DPG. The reliability scenario models are
created via Latin hypercube sampling with Cholesky
decomposition and scenario reduction. Numerical results
show that the proposed strategy can reduce the power flow
fluctuation with less ESS capacity, and increase the penetration
capacity of DPG in the distribution network while
maintaining the quality of the power supply. |
