Expected Outcomes:
The expected outcomes of this PhD project are set to be multifaceted and transformative for the field of power grid management. The research is grounded in a deep analysis of hydro-dominated power grid operations, with the investigation extending to a multitude of contingency scenarios impacted by weather effects, from severe and extreme conditions to longer-term climate change influences. A key aspect of the research lies in the development and validation of a multivariate machine learning model, meticulously crafted to enhance the accuracy of load and generation forecasting under weather conditions. The practical applications of this work extend into strategic planning and operational decision-making, providing utility operators with dynamic management tools that are particularly crucial for regions with weather volatility. However, the model is just one piece of a larger puzzle. The heart of the research lies in its comprehensive approach to understanding and improving power grid operations. The research is dedicated to evaluating weather-based security constraints, performing optimal power flow calculations, and enhancing the adaptability of power systems. The project aims to introduce pioneering early warning systems tailored for hydropower-centric grids, employing Security Constrained Optimal Power Flow (SCOPF) methodologies to navigate diverse weather conditions. Additionally, the research plans to develop new strategies for adjusting power generation and distribution – known as re-dispatch strategies – to keep the power grid stable and efficient, even during unexpected weather events. These strategies are crucial for making sure that power grids are not just reactive to disruptions but are also proactively managed in light of ongoing climate shifts.
