Abstract:
Integrating renewable energy sources into the modern grid has been challenging in terms
of maintaining grid stability and quality. Changes in renewable energy production and
fluctuating load demands have brought innovative methods for reactive power
compensation. This thesis discusses some adaptive reactive power compensation
algorithms for renewable energy integration and evaluates their effects on grid stability and
efficiency.
The main purpose of this thesis is to present an adaptive reactive power compensation
model that can dynamically adapt to changes in the grid. Advanced control algorithms that
can provide maximum power quality are targeted with STATCOM, which is selected as
the main compensation device. Within the scope of the research, the responses of
STATCOM under active grid conditions and the innovations in the grid to which it is added
at certain periods are investigated through simulation and calculation.
Adaptive control philosophy will be simulated using DIgSILENT to evaluate its
performance by looking at basic values such as voltage sharpness, power factor
optimization and energy efficiency, and necessary comparisons will be made and visuals
will be provided with graphics. In addition, within the scope of this thesis, it will be
investigated how a STATCOM can make a difference in performance compared to classical
compensation devices in terms of its advantages in cases where renewable energy is of high
importance.
The results obtained in all these stages show that the proposed adaptive control strategies
significantly increase the stability of the grid, especially under sudden changes in
renewable energy output. The important results obtained as a result of the thesis studies
emphasize the importance of adding intelligent control systems to reactive power
management for future electrical grids.
The innovative contributions in this thesis are threefold: comprehensive analysis of the
limitations of conventional techniques, formulation of an adaptive algorithm specifically
for renewable energy grids, and performance evaluation by proposing a framework for
multiple scenarios. Furthermore, by investigating the possibility of reduced losses with a
STATCOM-based system compared to conventional methods, this thesis further
emphasizes energy efficiency.
The research conducted in this study provides valuable insights into adaptive reactive
power compensation and its vital role in supporting the transition to sustainable energy
systems. The proposed framework not only addresses the urgent challenges of renewable
energy integration, but also lays a foundation for future work in the field of smart grid technologies and smart energy management systems. The current work bridges the gap
between theoretical development and practical application by proposing a robust solution
to improve grid stability in the renewable era.
