Technology Review of DC Power Distribution System in PEDF Buildings

In the wake of the wide application of distributed energy resources and the rapid development of renewable energy technologies, building energy systems are evolving in the direction of high efficiency, flexibility and sustainability. PEDF buildings are an emerging energy system that combines photovoltaic (PV) power generation, electrical energy storage, direct current (DC) power distribution, and flexible power technology to provide a solution for buildings to efficiently utilize renewable energy and optimize energy consumption. Its core is PV power generation technology, through the installation of photovoltaic panels on the exterior of the building, solar energy can be directly converted into electricity, and this way of utilizing renewable energy not only reduces the reliance on traditional energy sources, but also reduces the adverse effect on the environment. PV power generation systems can meet the electricity demand inside the building and store the excess power for future use. Electric energy storage systems typically use efficient battery technology to store and release electricity, increasing energy efficiency and reliability, and balancing the difference between energy supply and demand to provide a stable output of electricity. PEDF building systems provide a solution for the sustainable development of the building industry by efficiently utilizing renewable energy sources and optimizing energy consumption. This emerging building energy system lays the foundation for us to move towards a more environmentally friendly and sustainable future.
