In order to economically transfer electrical powers from generation-side to demand-side, these powers need to be transferred at high-voltage levels through suitable transmission systems and power substations.
To this end, high-voltage transmission systems and power substations are in demand. Actually, they are at the heart of interconnected power systems, in which any faults might lead to unsuitable consequences, abnormal operation situations, security issues, and even power cuts and blackouts. In order to cope with the ever- increasing operation and control complexity and security in interconnected high-voltage power systems, new architectures, concepts, algorithms, and procedures are essential.

An online multiprocessor scheduling multiprocessor with bounded speed MBS has been proposed in [6]. The comparative analysis shows that the multiprocessor with bounded speed MBS outperforms other algorithms.
The competitiveness of MBS is the least to date. In [7], a new hybrid control algorithm for the cascaded modular multilevel converter has been presented.
