A Monte-Carlo based, probabilistic power flow method is used to evaluate different power system interconnection options. Suitable indices are proposed to assess the potential profit of each interconnection scenario and the required interconnection rating. Separate investment perspectives are identified and the respective optimal solutions are compared. Indicative results are presented regarding...

The uncertainty of renewable energy sources (RESs) presents a challenge for power grid operation. To analyze the variability RESs, probabilistic flow (PPF) method has been introduced. This can be used to evaluate RES generation and its effects on system voltage flow. In this study, an analytical approach with PPF calculate line sensitivity by is proposed, which directly probability distribution...

In this paper, we present a new method to determine the optimal location and parameter settings of UnifiedPower Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC isconsidered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.This option gives to UPFC the power to control the voltage profile and transmi...

flexible ac transmission systems (facts) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. in this paper, in order to find type, size and location of facts devices in a power system a dedicated improved particle swarm optimization (dipso) algorithm is developed for de...
