Special Issue Information

Dear Colleagues,

Solar is becoming a new phenomenon in the energy market, offering the lowest cost of energy we have ever seen. Photovoltaic (PV) technology is expected to develop from infrastructure to fields, water to roads, roofs to façades, in deserts and urban areas, on cars, buses, trucks and planes; from nanogrids to super grids and as stand-alone or grid-connected technology.

The more PV develops, capturing a greater share of power generation, the more new challenges arise, needing to be tackled with technological developments in the various fields of PV systems. New solar technologies, such as floating PV, solar shingles and solar trees, can inspire new applications of PV systems. Converter topologies play an important role in the integration of PV with grid and energy storage devices. Smart-grid solutions, such as the application of IoT and machine learning techniques, are becoming critical for the successful integration of PV systems at various levels of power systems. From a distributed generation to large-scale PV plants, there is a requirement to develop consumer/utility-friendly grid codes. Large-scale PV generation demands for the reproduction of conventional generators so that they can take part in frequency regulation and automatic generation control. The cooperative control of PV systems and the hybrid operation of PV with storage systems is becoming essential due to the large penetration of PVs in the grid.

This Special Issue of Energies focuses on future technologies of photovoltaic energy systems for the operation of power systems.

The main topics of interest for this issue include, but are not limited to:

  • New solar technologies such as floating PV, solar shingles, solar trees and solar carports.
  • High-gain converters.
  • Module-based optimized PV system.
  • Hybrid converters for the application of PV and energy storage.
  • Large-scale PV integration to the grid.
  • Smart grid solutions to PV system.
  • Application of communication technologies, IoT and machine learning techniques for PV integration.
  • Requirement of new grid codes.
  • New applications of PV such as heating, cooling and EV charging stations.
  • DC microgrid applications.
  • Solar-powered transportation.

In low voltage (LV) distribution systems, the problem of overvoltage is common during the lower load intervals. This problem arises because of the high value of R/X ration of these systems. Many techniques are available in literature to cope up with this problem at the converter level; mostly these methods control the reactive or active power of the photovoltaic (PV) systems. However, there are certain restrictions and complications with the reactive power control of PV systems. Most of the active power control methods have been implemented at the inverter stage of the PV system, resulting in implementation complexities and excessive oversizing of the converter. Therefore, in this paper, a simple, de-rating based voltage control algorithm is proposed to overcome the problem of overvoltage. So far de-rating technique has been used to enable frequency support functions in PVs; in a first of its kind, de-rating technique is used here to control the voltages in PV rich LV distribution systems. The entire control is implemented on the dc/dc converter stage of the PV system and the inverter stage is kept untouched. The effectiveness of the control is verified by simulating a sample PV-rich three bus LV distribution system on the MATLAB software. The proposed control avoids the overvoltage by approx. 700 V for the best-case scenario. Full article

Microgrids have arisen as an alternate solution to the problem of power generation in distributed energy. Compared to ac microgrids, dc microgrids (DC MGs) are superior in terms of system efficiency, power quality, affordability, and ease of control. For the integration of renewable energy generation into microgrids, power electronic converters are required. When power electronics converters are tightly regulated, they behave as a constant power load (CPL) which exhibits a negative incremental impedance characteristic. As a result, oscillations occur in voltage response at a DC bus. To suppress the voltage oscillations in DC MGs, various damping stabilization techniques are proposed by researchers. This paper provides a comprehensive review on active damping stabilization techniques. To improve the system’s stability, active damping can be implemented in three distinct zones: source-side, load side or CPL side, and intermediate level. After analyzing each zone, their merits and drawbacks have been presented. Moreover, CPL modelling, performance of cascaded DC-DC systems, the effect of the load on the source subsystem, the effect of the source on the load converter, and stability analysis are discussed. Finally, concluding remarks and future research directions are highlighted. Full article

Presently, the world is undergoing exciting haste to install photovoltaic (PV) systems in industry, residential/commercial buildings, transportation, deserts, street lights, and many other applications. Solar photovoltaic energy systems are clean and reliable energy sources that are unlimited, unlike their fossil fuel counterparts. The energy market is rapidly growing globally with newly and cumulative installed capacities of about 37.6 GW and 139.6 GW, accounting for 53% and 55%, respectively, in 2017, making it one of the fastest-growing industries. The cumulative photovoltaic installations are projected to have reached 600 GW worldwide and are projected to reach 4500 GW by 2050 because of the strategies and policies of many countries. In 2021, more than three-quarters of the developed countries are now home to one solar installation. This article evaluates a critical and extensive review of the contributions of solar photovoltaic systems to national development. The approach follows all steps, starting with capturing photovoltaics on the Earth’s surface, then price reduction, load management, and socioeconomic impact of solar photovoltaic systems. From the study, it is found that the policies and strategies adopted by the leading countries, such as tax credits, capital subsidies, net-metering, VAT reduction, feed-in tariffs (FiTs), and renewable portfolio standards (RPS), have significantly helped in more installations. Additionally, the significant drop in photovoltaic module prices from 4731 $/W in 2010 to 883 $/W in 2020 has boosted the move for more installations. Based on the findings, approximately 10 million permanent employments would be put in place by advancing solar power across the globe annually. Full article
