Topical Collection Information

Dear Colleagues,

Distributed energy systems (DES), also called distributed generation or on-site generation when referring to electricity supply, refers to the electrical generation performed by a variety of small, grid-connected, or distribution system-connected devices, rather than transmitting energy over the electric grid from a large, centralized facility. This kind of systems use renewable energy (photovoltaic, wind power, small hydro, biomass, etc.) but they can also use fossil-fuel technologies (diesel generator, etc.), with power typically lower than 10 MW and in many cases hybrid systems (multiple generation and storage components) are used. Waste-to-energy, combined heat and power (CHP), and storage (batteries or other kinds of storage) are also included in this kind of system. DES increase energy efficiency, reduce carbon pollution, improve grid resiliency and security of supply and curtail the need for new transmission investments. Microgrids (localized, small-scale grids) are DES systems, strengthening grid resilience, and helping mitigate grid disturbances. They can disconnect from the centralized grid and operate in off-grid mode.

Taking into account all the above, this Special Issue is dedicated to any topic related to “Distributed Energy Systems”, grid-connected or off-grid systems, using renewable, fossil-fuel technologies or hybrid systems, with or without storage. It includes modeling, control, protection, operation, sizing, simulation, optimization, grid stability, and other issues, considering technical, or environmental aspects.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the collection website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2300 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this paper, the gradient temperature and the thermomechanical stresses of a photovoltaic panel has been studied with and without heatsink. For this purpose, a three-dimensional analysis was carried out. Accordingly, a heat transfer analysis was developed. The numerical results show a cooling close to 26.7% with the proposed triangle fins compared with the rectangular fins studied before by another author, and the temperature distribution was determined. With this information, the stress analysis was carried out in order to find the effect on the panel due to the thermomechanical stresses. The aluminium frame was restricted to move freely. The resulting stresses field established the magnitude of the alternative stresses, resulting in a 6.7% drop compared with a reference panel. The guidelines of IEC 61215 have to be take into account. Due to the results obtained, the use of this kind of system in desert conditions is desirable because of its high operational temperature and due to the increase in heat transfer by the fins.
