“…The growth of renewable energy sources and power electronics in use affects the quality of electricity. The most significant negative consequences of the deterioration of electricity quality are increased energy losses, reduction in the service life of electrical insulation, and malfunctions of relay protection and automation [43]. The total distortion of harmonics is the ratio between the fundamental harmonic and the higher-order harmonics.…”

Two prototypes with energy efficiency calculations have been developed to enable real-time efficiency assessment and data collection. The results of the experiment demonstrate that the use of microprocessor technology and the Internet of Things can significantly improve the efficiency and accuracy of energy audits in power transformers. The prototypes developed in this study provide real-time efficiency assessment and data collection, enabling more effective energy management and cost savings for industrial users. During the experiment, it was found that resonance can cause the same losses as a poor power factor of the system, highlighting the importance of addressing energy quality issues in addition to energy efficiency. These findings have important implications for energy efficiency policies and practices in the context of climate change mitigation and rising energy prices.

“…When single-phase multi-point access of distributed photovoltaic (PV) power generation in a region occurs, uneven installation and distribution of PV power and complex power flow will cause fluctuations in the regional distribution network, voltage rise or fall, three-phase imbalance, and an increase of harmonic current. It will easily cause abnormal operation or damage to distribution facilities, PV power generation equipment, and user equipment [2]. In order to meet the performance of the distribution grid and power supply requirements, it is generally adopted to adjust the transformer taps to increase the output voltage [3].…”

The integration of an Energy Storage System (ESS) is difficult to commercialize within the current Chinese market mainly because of the lacking of supporting policy and breakthrough technologies. However, it is considered an appropriate approach in a certain circumstance, for instance, in a remote rural area. This work presents a power-balanced ESS integration model and its control method. By using a rural distributed network in southern China, the results show that the proposed model is able to improve the three-phase power imbalance issue.

“…Energy quality problems have negative effects on the energy distribution system and consumers [1]. Energy quality problems cause energy losses in energy systems, decreased device life, noisy operation of devices, incorrect measurement of sensitive devices, damage of compensation systems, overload of transformers, decrease in insulation life, failures in relay protection and automation processes [2]- [7]. The electrical energy distribution system of university campuses and the quality of energy on campuses is an important issue.…”

In this study energy quality of university campus network have been analyzed experimentally. The experimental tests and measurements have been implemented at Engineering Building of the Bolu Abant Izzet Baysal University (Turkey). Energy quality analysis has been performed by making current, voltage, frequency, power factor, harmonics, neutral-earth voltage measurements at the main distribution board of the Engineering Building. Besides, active power filter has been connected and its effects examined. The reasons for the energy quality problems on the electric power distribution system of the campus building have been revealed and required solutions have been offered.
