Speech Title: Advanced Techniques for Enhancing Renewable Energy Integration into Power Systems

Abstract: Integration of renewable energy sources (RES) into power systems offers substantial shifting towards sustainable energy solutions, achieving energy transition and mitigating harmful gas emissions. However, the fluctuating characteristics of RES present significant obstacles to economic generation planning, grid stability and reliability. Because RES are site-constrained, transmission networks must be efficiently expanded considering the RES and grid flexibility measures. In this keynote speech, different real case studies are presented indicating the enhancement of RES integration through advanced and innovative techniques. Stochastic optimization approach was proposed to handle uncertain input data such as solar radiation, wind speed and load forecast in generation operation planning in which these input data are represented by different scenario tree branches weighted by their probability of occurrence. In addition, the voltage levels and fault-ride-through criterion have been maintained by involving reactive power compensation and advanced grid-forming inverters.

RES are connected to the power system via a power electronic-based inverters that do not bring additional inertia to the power system and then limit the system ability to reduce the change in power system frequency after any imbalance. Advancements in energy storage and ancillary service, such as battery, hydrogen and pump storage, have boosted the system’s stability and reliability. Moreover, advanced techniques for fast fault detection and tripping are highly effective in maintaining power system stability by minimizing the duration and impact of system disturbances. Upgrading the electric grid and building new substations allows power to flow from the rich RES areas. Recent research indicated that integrating RES and utilizing grid flexibility have improved system performance and significantly reduced grid losses and reinforcement costs. In addition, excess RES electricity can be converted into other energy carriers such as hydrogen production via electrolysis. Unlike batteries, hydrogen storage does not lose energy over time and could be used to transfer the abundant clean energy from season to another. This means that high renewable generation can only be achieved with seasonal storage. The obtained test results indicated that integrated planning of both electric and gas networks (IPEGN) was recommended to save the total expansion cost compared to individual separate network planning.
