AC/DC Hybrid Distribution System Optimization
Summary
AC/DC hybrid distribution systems integrate alternating-current and direct-current networks to accommodate a growing array of renewable generators, energy storage units, electric vehicles and DC-native loads. Optimisation in this context addresses both planning and real-time operation, seeking to minimise total losses, enhance voltage stability and maximise hosting capacity for intermittent resources. Core strategies encompass the siting and sizing of converters, network reconfiguration to balance power flows, and coordinated control of voltage-source converters or solid-state transformers. Economic dispatch models are extended to multi-objective formulations that trade off operating cost, power quality and reliability under uncertainty. The adoption of medium-voltage DC links within established AC feeders offers significant efficiency gains by reducing conversion stages and enabling higher transfer capacity. Globally, such hybrid architectures are driving more resilient urban distribution networks, smarter microgrids and cost-effective integration of largescale photovoltaics and wind farms. Practical applications span from data-centre power islands to interconnected city grids, supporting decarbonisation and accelerating the energy transition.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
