Special Issue Information
Dear Colleagues,
In order to achieve carbon neutrality, there is no doubt that classic fossil-fuel-based power generation should be replaced with renewable energy sources that do not emit greenhouse gases. However, apart from the unique advantages of green electricity production, the grid connection of the large capacity of renewable power sources creates various problems from the perspective of grid control, operation, and planning. These problems are mainly due to the uncontrollability of the output, which is called intermittency or variability. This might seriously threaten the stability, reliability, and safety of the power grid, which are considered the gold standard for conventional power grid operation, and can cause great confusion in economic dispatch in the short term, and optimal investment planning in the long term in terms of economics.
Each of the issues related to stability, reliability, safety, and economics is often presented in terms of inertia, voltage restoration, flexibility resources, and hosting capacity. For the contingency analysis, the replacement of classical generators by converter-based renewable power sources would reduce the inertia of the grid, making it difficult to maintain frequency against fault. In addition, the self-protection operation of converters during faults might disconnect renewable sources from the grid, causing a shortage of resources for frequency and voltage restoration after the fault clearing. Even under steady-state conditions, forecast errors in the future output of renewable sources, which should be dependent on forecasting, require supply flexibility from controllable sources to ensure supply reliability. Finally, more economic and systematic planning should be carried out regarding the expansion of grid facilities to accommodate renewable power sources.
Research areas may include (but are not limited to) the following:
- Renewable generation forecasting;
- Virtual inertia;
- Grid-forming inverter;
- Energy storage application;
- Dynamic voltage restoration;
- Renewable generation monitoring system;
- Hosting capacity expansion of the grid;
- Renewable generation curtailment;
- Sustainable energy mix;
- LCOE (levelized cost of energy) of renewable generation;
- Flexibility of the grid;
- Sector coupling;
- Load flexibility (DR, plus DR, V2G, etc.).
We look forward to your participation and contributions.

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 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. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.
