Gauss-Seidel-Patel Loadflow (GSPL) computation method is invented involving self-iteration over a node within global iteration over (n-1) nodes in n-node power network. Also invented is a network decomposition technique referred to as Suresh's diakoptics that determines a sub-network for each node involving directly connected nodes referred to as level-1 nodes and their directly connected nodes referred to as level-2 nodes and so on, wherein the level of outward connectivity for local solution of a sub-network around a given node is to be determined experimentally. Sub-networks are solved in parallel, and local solution of sub networks are related into network wide global solution using an invented technique. These led to the invention of the best possible parallel computer - a server-processor parallel-processors architecture wherein each of the parallel processors communicate only with the server processor, commonly shared memory locations, and each processor's private memory locations but not among themselves.

L'invention concerne un procédé permettant de réaliser des calculs de transit de puissance pour réguler les tensions et le débit de puissance dans un réseau de distribution électrique, consistant à optimiser les opérations du réseau de distribution électrique. Ce procédé consiste plus précisément à obtenir des données de puissance en ligne, concernant l'état actuel des commutateurs/disjoncteurs, puis à calculer le transit de puissance pour réguler le débit de puissance à l'aide d'un moyen de régulation, afin qu'aucun composant du réseau de distribution électrique ne soit surchargé, et pour réguler les tensions, afin qu'il n'y ait pas de surtensions/sous-tensions au niveau des noeuds du réseau, suite à des perturbation de courte ou de longue durée.
