This review compiles a total of ninety studies conducted and published between 2019 and 2025, presenting for the first time an integrated approach that simultaneously optimizes the generation, transmission, storage, and flexibility of resources given high ratios of renewable generation. We present. This paper examines the technological and economic dimensions of AC, DC, and smart grids, concentrating on the optimization of costs, efficiency, stability, and scalability. Smart grids, enhanced by AI, IoT, and blockchain technologies, play a vital role in energy management optimization. To integrate renewables into grids and support the energy transition, operators may need to rethink their planning approaches and tools to tackle network and value chain challenges. Power grids are the foundation of energy systems, playing a key role in the energy transition by enabling the use of.
