“…K-means algorithm is a unsupervised learning method in machine learning, which can mine the similarity of data objects without any experience to achieve the purpose of data grouping. 27 This algorithm requires pre specifying the number of clusters K and K initial clustering centers, calculating the distance between the given data object and the initial clustering center, and dividing each data object into the closest cluster. After all data objects are allocated, the average value of data objects for each type of cluster is recalculated as the new clustering center.…”

“…Apart from MGs involving only power sector, integrated MEMGs have recently attracted much interest in terms of energy management owing to their various advantages, such as increased system reliability and efficiency, reduced fuel consumption, energy cost, and carbon emissions [4]. For instance, in [14], a two-stage stochastic optimization approach based on scenario analysis is proposed for the energy management of MEMGs, considering the stochastic processes of wind power generation and demand profiles. In [15], an adjustable and robust formulation is developed for the optimal energy management of MEMGs, capturing uncertainties associated with energy demand and RESs.…”

“…To highlight the contributions of this paper, existing literature associated with the energy management problems of both MG and MEMG has been systematically organized in Table 1. On one hand, compared to the model-based optimization methods [9][10][11][12][14][15][16][17][18][19], this paper employs a model-free safe RL method that can learn the energy management control policy of an MEMG, while ensuring the secure network operation. On the other hand, compared to the existing RL methods [7,22,[24][25][26][27][28][29][30][31]33,34], a significant research gap has been identified, which drives the motivation behind this paper: no previous work has developed a safe and automatic control method for the realtime energy management of MEMGs that can satisfy all the physical constraints pertaining to the MEMG model.…”

“…Currently, two predominant research methodologies are employed to address the uncertainty inherent in integrating clean energy into the power system. These are stochastic optimization (SO) [11][12][13][14] and robust optimization (RO) [15][16][17][18]. Each method provides strategic frameworks for managing the unpredictable nature of clean energy outputs.…”
