Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Building a power system with a high penetration of renewable energy is the prevailing developmental trajectory of most countries. However, the current electricity spot market mechanism is predominantly tailored for conventional generators (CGs, e.g., thermal units), which ignores the notable differences between renewable energy sources (RESs) and CGs in terms of generation cost and adjustment capability. Consequently, RESs benefit from priority in market-clearing without assuming regulation responsibility during the bidding process alongside CGs, thereby impacting the fairness of the spot market. In this paper, we propose the concept of RES generation directrix (RGD) to quantify the regulation responsibility that RESs need to bear when participating in the spot market. Subsequently, a regulation energy market is introduced in the spot market to reshape the power generation curve of RESs. Finally, the validity of the proposed market mechanism is verified across different test systems. Numerous experiments indicate the proposed RGD-based market mechanism provides a more level playing field for RESs and CGs, helps form an independent offer price for RESs, thereby relieving the “missing money” problem and prolonging the effectiveness and sustainability of electricity spot markets.
