Optimal Design for Renewable Power Systems

Dear Colleagues,

At present, renewable energy sources (R.E.S., i.e., wind turbines, photovoltaic plants, small hydroelectric plants, geothermal plants, etc.) are applied to power systems mitigating the operation of classical thermal power plants improving the environment and limiting greenhouse gases. However, the R.E.S. growth provokes serious issues on power systems, such as the increase of the fault current level, operation problems on protection systems, power quality issues, power system stability issues, etc. Therefore, research and development activities on the optimal design of power systems with significant penetration of R.E.S. have become exceptionally energetic during the last decade.

Thus, to further spread the technologies and methods related to optimal design of power systems with significant penetration of renewable energy sources, this Special Issue, entitled “Optimal design for renewable power systems”, has been proposed for the international journal Processes, which is an SSCI and SCIE journal (with a growing CiteScore from 2.4 to 3.5). This Special Issue mainly covers original research and studies related to the above-mentioned topics, including but not limited to energy systems (energy system planning; energy system transition; changes in energy demand; energy and electricity markets); automation control systems (process automation and monitoring; artificial neural networks; fault detection and diagnosis; intelligent control systems; system condition monitoring; optimization algorithms;) and so on. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Energy system planning: power system design with R.E.S.; hybrid energy system (with R.E.S., thermal units, etc.); autonomous energy system (i.e., island, ship); optimization algorithms for the power system design.
• Energy system transition: design of hydrogen networks, residual cost of oil / natural gas networks, high voltage direct current transmission links for offshore wind parks, etc.
• Design of new devices: gas turbines, hydro-turbines, fuel cells, efficient electrical machines, co-generation, etc.
• Changes in energy demand: influence of new parameters (i.e., pandemic, Ukrainian crisis), short-term, mid-term, long-term energy/power forecasting (with regressive models, artificial intelligence, fuzzy logic, etc.); demand side management; energy saving; demand for co-generation; energy storage systems; use of electric vehicles; port electrification (cold ironing).
• Energy and electricity markets: new trends in spot pricing; optimal power operation; economic dispatch; smart grids; changes in energy production through the stochastic behavior of R.E.S.
• Reliability studies: bottom-up reliability analysis for renewable energy sources; expected loss of load power and of load energy for energy systems.
• New technologies for automatic control of renewable energy sources and of energy systems.
• Condition monitoring for wind turbines, small hydro-power plants, etc.
• Fault detection, diagnosis and protection for power systems with R.E.S.
• Control strategy for R.E.S. releasable reserve power.

Papers selected for this Special Issue are subject to a rigorous peer-review procedure with the aim of rapid and wide dissemination of research results, developments, and applications.

We are writing to invite you to submit your original work to this Special Issue, and look forward to receiving your outstanding research.
