How to directly connect photovoltaic panels to variable frequency air conditioners

Can PV array and Bes reduce power consumption of air conditioning unit?

In this paper, considering such facts and taking the benefit of the VFD technology, an energy management methodology is proposed using PV array and BES to reduce the power consumption of air conditioning unit as well as it feeds excess PV generation to the grid with improved power quality.

How does a PV panel & BES work?

The DC power produced by the PV panel and BES is fed to DC bus of the VFD directly with the help of dual active bridge (DAB) converter, that eliminates DC-AC conversion stage. A voltage source converter (VSC) is interfaced as a front-end converter of VFD, to feed PV generation to the grid when air conditioner is not operating.

What is the PVF of an air conditioner?

The PVF is the ratio of the total seasonal PV generation to the total seasonal electricity consumed by air conditioner. If the PVF is 1, the total seasonal PV generation is equal to the total seasonal electricity consumed by the air conditioners.

What are the benefits of PV driven air-conditioner systems?

Due to the strong correlation between photovoltaic (PV) generation and building cooling demand in summer and the ever-decreasing cost of PV modules, PV driven air-conditioner systems have an unrivaled advantage in reducing the energy consumption of office buildings and reducing the peak load of the utility grid [1 ].

What is the energy potential of photovoltaic direct-driven air conditioners?

Zero energy potential of photovoltaic direct-driven air conditioners with considering the load flexibility of air conditioners Parametric analysis and optimisation of energy efficiency of a lightweight building integrated with different configurations and types of PCM Renew. Energy, 168 ( 2021), pp. 865 - 877, 10.1016/j.renene.2020.12.112

Can PV generation reduce energy consumption from utility grid?

In this paper, PV generation is utilized with a battery energy storage (BES) for an air conditioner to reduce the impact of energy consumption from utility grid. Recently, air conditioning units are adopted with variable speed drive (VFD) that creates peaky nature of the input grid current due to the AC-DC conversion.
