Abstract
This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of authors due to scientific errors reported by authors. The author reported errors are: 1: In the “5.1 Case Description” section, Fig. A1 (wind and PV output power) is the input data for the simulation calculation. The authors report that, due to an oversight, they did not use real wind and PV output power data, which would lead to inaccurate results for the system simulation calculations. 2: For the “4 Model solving algorithm”, the authors found that it is incorrect to use the properties of Gaussian functions to improve the CDE algorithm because Gaussian functions do not have the properties of concave functions. This is evidenced in the literature “DOI: https://doi.org/10.13335/j.1000-3673.pst.2020.1720”. 3: Fig. 8 (Iterative Convergence Curve of Rastrigin Function) is tested using the benchmark test function (Rastrigin function) in order to demonstrate the feasibility of the GCDE algorithm. However, it is clear from Point 2 that the GCDE algorithm is wrong. Therefore, the authors re-examined the original program and found that they did not compute it with the GCDE algorithm before, but with the CDE algorithm. Therefore, Fig 8 is a logical error. 4: In the VPP optimization objective function of “Cost of wind and PV abandonment penalties”, this cost should not be taken into account. Because the power not used by wind and PV is for P2G use. And P2G can generate revenue for the system. Therefore, it creates precisely the revenue, not the cost. This can lead to the creation of a wrong mathematical model. The authors apologize for any inconvenience this may have caused to the readers of the journal.
