Performance Analysis of a DC Nanogrid Heat Pump System for Residential House

The increasing demand for energy-efficient systems has led to the exploration of Direct Current (DC)-powered technologies in residential applications, as most residential appliances and devices now run on DC voltage. The future of renewable energy integration will depend heavily on powering the planet with DC voltage because most distributed energy systems (PV panels, batteries, etc.) are DC-driven. For this reason, energy efficiency in buildings is today a prime objective, among building services, the growth in HVAC systems energy use is particularly significant (50% of building consumption and 20% of total consumption in the USA.
