      abstract = {Saudi Arabia is making the shift from a centrally controlled electricity system that is based on hydrocarbons to one that is digitally coordinated, in which large-scale solar and wind power, distributed energy resources, storage systems, flexible demand, and power-electronic interfaces interact throughout both the transmission and distribution networks. This change results in a systems issue rather than just a problem relating to power generation: it is necessary to forecast and balance the variability, to manage the low-inertia characteristics, to respect the network's capacity limits, and at the same time to ensure that the increasingly digital control systems remain interoperable and secure. This review carefully brings together peer-reviewed evidence published between 2020 and 2025 in order to look at the engineering, operational and governance needs for incorporating renewable energy into Saudi smart grids. Thirty studies verified by DOI were chosen using a structured process for evidence synthesis, combining research that is specific to Saudi Arabia with internationally applicable work on optimal power flow, demand response, energy storage, grid-forming control and learning-based optimisation. The evidence shows that no single technology can solve the issue of integrating renewables. Real advances require coordinated forecasting, scheduling that takes uncertainty into account, storage and demand flexibility, improved grid-code functions, management of distributed resources and validated real-time optimisation. Key priorities in Saudi Arabia include providing frequency support during times of low demand, using climate considerations in the modelling of assets, ensuring observability of the transmission and distribution networks, achieving interoperable control of distributed energy resources and carrying out a staged rollout of grid-forming capabilities. The review suggests an integrated architecture together with a transition roadmap that connects the physical assets, digital intelligence, market signals and resilience controls. Future research should move from isolated test systems to systems that are calibrated for Saudi conditions, involving cyber-physical and hardware-in-the-loop validation and including clear reliability, economic and security metrics.},
