Special Issue Information

Dear Colleagues,

Nowadays, due to rapid resource depletion and environmental issues related to fossil energy, people are gradually beginning to pay more attention to the development and utilization of renewable energy and multi-energy sources, such as wind, solar, and hydro, etc. However, with more and more renewable energy sources integrated into power grid, the normal operation and deployment of power grid are faced with many challenges, and the integration of renewable energy and multi-energy sources is very valuable. Power electronic technology plays an important role in integration, and power electronic converter topologies and controls are the focused of this Special Issue.

This Special Issue, entitled “Power Electronic Converter Topologies and Control for Integration of Renewable Energy and Multi-Energy Sources”, invites you to submit papers on areas including, but not limited to, the following interesting topics:

Power electronic converter topologies in renewable energy integration;
Control strategies for efficient energy conversion and management;
Modelling, simulation, system stability and reliability;
Characteristics of renewable energy sources on power conversion;
Conversion technologies for renewable energy and energy saving;
Power quality and harmonic controls;
Integration of renewables using advanced power electronics control schemes;
Static and dynamic power transfer laws of renewable energy systems;
Grid integration techniques for renewable energy sources;
Multi-energy system integration and optimization;
Power quality issues and mitigation techniques in integrated energy systems.

Abstract

This paper introduces a cascaded symmetrical non-isolated high step-up voltage gain converter with high efficiency and low voltage stress on components combining a non-isolated buck-boost converter and voltage doubler structure. In the proposed converter, the input source is connected in series to the output load; hence, a part of the source energy is directly delivered from source to load, not through the switching branch, improving efficiency. Furthermore, the appropriately stacked voltage doubler stage not only amplifies the high step-up voltage gain ratio but also considerably diminishes the voltage stress on all semiconductor devices and capacitors. As a result, the costless low internal resistance and low voltage components can be employed for higher efficiency, higher power density, and lower cost. To demonstrate the practicality of the proposed topology, the operating principle is outlined, and the steady-state characteristics are thoroughly analyzed. Furthermore, a 360 W prototype converter has been fabricated to confirm the efficiency of the proposed converter. Full article

Abstract

Oil–paper insulation is the critical insulation element in the modern power system. Under a harsh operating environment, oil–paper insulation will deteriorate gradually, resulting in electrical accidents. Thus, it is important to evaluate and monitor the insulation state of oil–paper insulation. Firstly, this paper introduces the geometric structure and physical components of oil–paper insulation and shows the main reasons and forms of oil–paper insulation’s degradation. Then, this paper reviews the existing condition assessment techniques for oil–paper insulation, such as the dissolved gas ratio analysis, aging kinetic model, cellulose–water adsorption isotherm, oil–paper moisture balance curve, and dielectric response technique. Additionally, the advantages and limitations of the above condition assessment techniques are discussed. In particular, this paper highlights the dielectric response technique and introduces its evaluation principle in detail: (1) collecting the dielectric response data, (2) extracting the feature parameters from the collected dielectric response data, and (3) establishing the condition assessment models based on the extracted feature parameters and the machine learning techniques. Finally, two full potential studies are proposed, which research hotspots’ oil–paper insulation and the electrical–chemical joint evaluation technique. In summary, this paper concludes the principles, advantages and limitation of the existing condition assessment techniques for oil–paper insulation, and we put forward two potential research avenues.
