METHOD AND APPARATUS FOR PARALLEL LOADFLOW COMPUTATION FOR ELECTRICAL POWER SYSTEM

摘要

Gauss-Seidel-Patel Loadflow (GSPL) computation method is invented involvingself-iteration over a node within global iteration over (n-1) nodes in n-nodepower network. Alsoinvented is a network decomposition technique referred to as Suresh'sdiakoptics thatdetermines a sub-network for each node involving directly connected nodesreferred to aslevel-1 nodes and their directly connected nodes referred to as level-2 nodesand so on,wherein the level of outward connectivity for local solution of a sub-networkaround a givennode is to be determined experimentally. Sub-networks are solved in parallel,and localsolution of sub networks are related into network wide global solution usingan inventedtechnique. These led to the invention of the best possible parallel computer -aserver-processor parallel-processors architecture wherein each of the parallelprocessorscommunicate only with the server processor, commonly shared memory locations,and eachprocessor's private memory locations but not among themselves.
