This study explores the integration of Wind Turbine Generator (WTG) into the
electric power grid, addressing challenges caused by their intermittent output
power, which can lead to instability. The intermittent nature of wind energy and the
reduced inertia of wind turbines present significant challenges in maintaining power
system stability, especially during network faults and transient events. The
intermittency affects grid stability, requiring additional measures for network
balancing and energy storage. This research introduces a Power Oscillation
Damping (POD) control scheme, coupled with battery energy storage, to enhance
system stability following network disturbances. This innovative scheme integrates
a POD controller for WTG and a battery, achieving faster oscillation damping than
systems without battery integration. The control strategy for WTG focuses on active
power management through the surplus power of the wind turbine's kinetic energy.
The phase angle from the interconnection point has been used as the feedback. On
the other hand, reactive power to achieve the oscillation damping is taken from the
speed of the closest synchronous generator as the feedback. Feedback mechanisms
for these control loops allow for coordinated and effective control responses.
Incorporating a battery into the same POD scheme can help mitigate active or
reactive power fluctuations and overall stability, effectively compensating for the
impacts during and after disturbance events. The effectiveness of the proposed
control scheme, enriched by the integration of battery energy storage, is validated
using the PSCAD simulator across four different scenarios in a two-area power
system with long transmission lines. The results demonstrate a significant
improvement in power system stability, highlighting the substantial benefits of
integrating battery storage and strategically designed control schemes for WTG to
ensure power system stability, especially following network disturbances.
Additionally, Prony analysis determined that damping ratios validate the WTG-
battery system's remarkable damping characteristics, significantly improving
oscillation damping and stability across various scenarios. This study contributes to
developing advanced strategies for continuously integrating renewable energy
sources into the grid, particularly in systems characterized by weak grid systems
and long transmission lines. |
