Abstract:
Wind power penetration is rapidly increasing in the contemporary world. As
penetration levels rise, new issues emerge in terms of the various effects they produce
on the transmission network. It is of utmost importance to assess these impacts to
ensure smooth and reliable operation of the electrical grid. Throughout this age,
transmission network operators have formulized a variety of frameworks and tactics
to account for the effects of integrating wind energy resources. In this study, numerous
transmission network effects of high wind power penetration have been examined, and
a general overview of issues with large-scale wind farm integration is provided.
MATPOWER is used to run a single period AC Optimal Power Flow (AC OPF) on an
altered version of IEEE-118 bus test case under various levels of wind power
penetration to examine the effects on voltage profile, locational marginal prices
(LMPs), congestion, line losses, and overall cost of generation. Furthermore, to
analyze the impact of energy storage system (ESS) on wind integrated transmission
system, a network constrained deterministic unit commitment using a multiperiod DC
Optimal Power Flow (DC OPF) design is performed in MATPOWER Optimal
Scheduling Tool (MOST) on the same test case resulting in a mixed integer
optimization problem involving mixed integer quadratic programming (MIQP) solved
using Gurobi.
