More Information
Summary:The invention discloses a load flow calculation method of a power system containing distributed power supplies based on intelligent search. The method comprises the steps of enabling an equivalent active load P1 and an equivalent reactive load Qi of each network node in a power system to be equivalent with resistance Ri and reactance Xi, first setting voltage of each network node as rated voltage, applying the intelligent search for solving the equivalent variables Ri and Xi of each node, enabling the equivalent active load and the equivalent reactive load that are consumed on the Ri and Xi of each node to be equal to the actual equivalent loads Pi and Qi, and solving the network load flow. The invention has the advantages of being capable of achieving network load flow calculation of a multi-power supply, multi-weak ring network, and multi-node type power system with DG.
