Special Issue Information

Dear Colleagues,

Abstract:

Integrated renewable energy generation systems have numerous advantages and benefits compared to conventional energy generation systems, such as decentralized energy production, environmental impact reduction, and better energy security. Renewable energy systems can be classified under the following categories: solar, wind, hydroelectric, biomass, chemical, geothermal, and ocean. Integration of these renewable energy resources can bring sustainable solutions and multiple products. Numerous energy system applications are available for possible combinations such as synthetic fuel production, absorption cooling, space heating, desalination, thermal energy storage, fuel cells, and thermochemical cycles. The selected integrated system can generate a large amount of electricity to supply the needs of human society, such as transportation and industrial production, and can alleviate the pollution of the world's environment and provide an effective solution to the future emission peak and carbon neutrality.

Aims and scope:

This Special Issue, “System Integration of Renewable Energy Generation”, seeks to promote and disseminate knowledge on the various topics and technologies of renewable energy generation and its systems integration. The journal aims to serve researchers, engineers, economists, manufacturers, NGOs, associations, and societies to help them keep abreast of new developments in their specialist fields.

“System Integration of Renewable Energy Generation” is an international, multi-disciplinary journal in renewable energy engineering and research. The journal aims to be a leading peer-reviewed platform and an authoritative source of original research and reviews related to renewable energy generation.

This article introduces a new control strategy for a bidirectional DC/DC converter used in photovoltaic energy storage systems (PV-ESSs), aimed to address the DC bus voltage deviation problem. The purpose of this paper is to design and practically implement a robust continuous control set predictive current control (CCS-PCC) method based on a nonlinear disturbance observer (NDO) to tightly regulate the common DC bus voltage in islanded DC microgrids. The CCS-PCC controller is used to replace the current loop PI controller, which effectively overcomes the shortcomings of the traditional linear lag control and improves the dynamic performance of the system. At the same time, the CCS-PCC method solves the inherent defect of finite control set predictive current control (FCS-PCC), where the switching frequency is not fixed. It effectively reduces the current ripple and realizes constant frequency control. In order to effectively suppress the DC bus voltage fluctuation during transients, the nonlinear disturbance observer is designed and combined with CCS-PCC. The feedforward method based on the NDO was utilized to enhance the disturbance rejection capability of the system. The simulation and experimental results show the feasibility and effectiveness of the proposed CCS-PCC+NDO approach, both during transient and steady-state operating conditions. Full article

Inductance is a necessary device for a grid-connected converter (GcC) to attenuate the switching-frequency harmonics in injected grid currents. However, in practice, the inductance decreases with an increase in output current. Especially when the amplitude of sinusoidal currents is higher, the inductance will vary over a wide range as the current value changes in a period. This variation may lead to system instability and cause output current fluctuation. To solve this issue, the model of the GcC with a proportional resonant regulator is firstly built, and the system stability with different current values is analyzed using the Nyquist criterion. The results show that the system stability decreases with an increase in current absolute value. Further, a loop gain compensation unit is embedded into the current regulator to maintain the loop gain constant and ensure the stability of the system under a wide variation range of current values. With this scheme, the compensation unit is only determined by the rated value and the non-linear characteristic of the filter inductance. Therefore, the loop gain compensation unit is independent of the original control system, and the traditional controller parameter design method can also be inherited. Finally, the simulated and experimental results from a 50 A static var generator (SVG) with wide filter inductance variation (using Mega-Flux core) have verified the correctness of the analyses and the effectiveness of the proposed method in this paper.
