Simulation Study of the Control Strategy of a DC Inverter Heat Pump Using a DC Distribution Network

Photovoltaics, energy storage, direct current and flexibility (PEDF) are important pillars of achievement on the path to manufacturing nearly zero buildings (NZEBs). HVAC systems, which an part public buildings, play a key role in adapting PDEF systems. This research studied basic principles operational control strategies DC inverter heat pump using distribution network with aim contributing development application small Along characteristics different operating conditions, has ability adapt changes bus voltage adds system. Theoretical models integrated ice storage unit were developed. The system considered influence both room temperature varied voltage. A simulation study was conducted MATLAB & Simulink software results validated by experimental data. showed that: (1) fluctuation under rated working had little effect operation unit; (2) When fluctuating from 80%–90% or 105%–107%, could still operate normally reducing frequency; (3) less than 80% more 107%, needed be shut down for sake equipment safety, so that device adjust sharp decrease rise
