Stability and Control of Power Grids Integrated with Renewable Energy Sources

Dear Colleagues,

Nowadays, it is difficult to imagine our society without electricity, but obtaining electricity means, in some cases, such as fossil fuels or nuclear energy, a considerable carbon footprint, which is detrimental in the fight against climate change. Renewable energy sources, such as wind power, solar power, bioenergy, and hydroelectric power, are natural and self-renewable, and they usually have a low- or zero-carbon footprint. Renewables' percentage of total power generation is quickly increasing, both in industrialized and in developing countries. Furthermore, several countries have effective strategies for converting their power sectors to renewables. To achieve these goals, the layout and operation of current power grid infrastructures will need to be reconsidered as the proportion of renewable energy generation grows.

The incorporation of a considerable number of variable renewables into electricity networks necessitates significant changes in order to increase the flexibility of existing systems in numerous directions. The first direction is to allow electricity flow, not only from centralized power plants to users, but also from small users or producers to the grid, which is aimed at ensuring grid stability when installing distributed generation; the second is to establish intelligent grid and demand management mechanisms; the third is to improve grid interconnection at the regional and international level, with the aim of increasing balancing capabilities, flexibility, stability, and the security of the supply; and the last is to introduce energy storage capacity to store electricity (energy) from variable renewable generation sources when the production exceeds the demand.

This Special Issue intends to describe and communicate the most recent achievements in the theory, design, modeling, stability, and control of power grids that incorporate renewable energy sources.

Topics of interest for publication include, but are not limited to, the following:

• All aspects referring to the design, modelling, and use of renewable energy sources;
• Establishing intelligent power grid;
• Electricity flow control;
• Improving grid interconnection;
• Developing energy storage capacity;
• Stability and control of power grids;
• Power quality in power grids;
• Fault detection;
• On-grid and off-grid condition monitoring techniques;
• Optimal design methodologies;
• Advanced modelling approaches.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue 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. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
