Special Issue Information

Dear Colleagues,

Energy, water resources, commodities production, scientific knowledge and technological expertise are the basis of the development of modern industrial and post-industrial societies. The recent economic developments implying large-scale industries and inducing large urban concentrations tend to require fairly concentrated energy supplies. Large interconnected systems have been successful in providing these supplies based on renewable energy generation, wherever there is potential for the latter. An often-referenced answer for the issue of expanding demands for energy and decreasing energy sources is to tap the energy from the Sun.

Solar energy systems like photovoltaic (PV) systems and concentrated solar power (CSP) advancements are some of the main renewable energy sources (RESs) that convert solar energy into power in a climate-friendly way and represent a free energy source. As of late, among all of the CSP system types, the central tower receiver (CTR) innovation draws broad consideration as a promising contender for enormous solar thermal plants in view of its high productivity coming about because of its high working temperature. The benefits and cost decrease of solar energy systems, particularly PV systems, has prompted rapid expansion in the combination of PV systems in recent years. Be that as it may, the high entrance level of solar PV systems affects the system's power quality because of the disparity between demand patterns and solar resources. These drawbacks limit the high infiltration levels of PV systems. Thusly, PV itself might present another challenge to the electrical framework rather than being a piece of the solution. Additionally, the planning and demonstration of solar energy systems, especially central tower receiver power plants (CTRPPs), have numerous troubles assuming all specialized boundaries are considered.

The development and rapid deployment of solar systems worldwide raise the question of materiality, climate resilience, water consumption and land use for producing, using, and decommissioning the technology. The whole technology chain requires materials and consumes energy to producerequiring special attention to avoid rearranging rather than solving the energy problem. The high penetration of solar systems, representing intermittent resources, calls for a better management of other more stable clean energy resources such as hydropower. The intermittency of solar will also be impacted by the future climate changes that will present broad variations depending on regions. This Special Issue is open to all contributions advancing the knowledge on the climate, land, energy, water, and material use (CLEWm) nexus.

The presented work contains the comparison of a different photovoltaic system approach, in terms of monthly energy production profiles, with detailed user needs profiles. Two types of investors were taken into account—a company where the yearly energy consumption exceeded 50 MWh and a standard household where the yearly energy consumption was around 6 MWh. Moreover, two different scenarios were considered; the first one was focused on the maximization of the energy production during a year by choosing optimal azimuth and tilt angles, whereas the second PV system was based on the East–West azimuth angles, which usually enables one to have better energy self-consumption, which leads to sustainable energy usage. Energy production profiles, along with users’ energy needs profiles, were analyzed in terms of sustainability, investment payback time, and energy loss in the face of the new Polish Renewable Energy Law. Recent changes in the Renewable Energy Law in Poland, which came into force on the 1 April 2022, have changed the way many investors are thinking about investing in photovoltaic systems. The main difference is how the Energy Distributor is obliged to trade the photovoltaic electrical energy injected into the grid by Prosumers. The so-called “net metering”, which is kind of a barter deal, was changed to “net billing”—selling energy at a wholesale price. Net billing is believed to be less profitable than net metering due to a significant price difference between the bought and sold energy. Full article

This paper proposes an effective approach to solve renewable distributed generators (RDGs) and electric vehicle charging station (EVCS) allocation problems in the distribution system (DS) to reduce power loss (PLoss) and enhance voltage profile. The RDGs considered for this work are solar, wind and fuel cell. The uncertainties related to RDGs are modelled using probability distribution functions (PDF). These sources’ best locations and sizes are identified by the voltage stability index (VSI) and political optimization algorithm (POA). Furthermore, EV charging strategies such as the conventional charging method (CCM) and optimized charging method (OCM) are considered to study the method’s efficacy. The developed approach is studied on Indian 28 bus DS. Different cases are considered, such as a single DG, multiple DGs and a combination of DGs and EVs. This placement of multiple DGs along with EVs, considering proper scheduling patterns, minimizes PLoss and considerably improves the voltage profile. Finally, the proposed method is compared with other algorithms, and simulated results show that the POA method produces better results in all aspects. Full article

To satisfy global electrical energy requirements, photovoltaic (PV) energy is a promising source that can be obtained from the available alternative sources, but partial shading conditions (PSCs), which trap the local maxima power point instead of the global maxima peak power point (GMPP), are a major problem that needs to be addressed in PV systems to achieve the uninterruptable continuous power supply desired by consumers. To avoid these difficulties, a marine predator algorithm (MPA), which is a bio-inspired meta-heuristic algorithm, is applied in this work. The work is validated and executed using MATLAB/Simulink software along with hardware experimentation. The superiority of the proposed MPA method is validated using four different PSCs on the PV system, and their characteristics are compared to those of existing algorithms. The four different PSC outcomes in terms of GMPP are case 1 at 0.07 s 995.0 Watts; case 2 at 0.06 s 674.5 Watts; case 3 at 0.04 s 654.1 Watts; and case 4 at 0.04 s 364.2 Watts. The software- and hardware-validated results of the proposed MPA method show its supremacy in terms of convergence time, efficiency, accuracy, and extracted power. Full article
