Abstract
En 中文
The increased penetration of intermittent distributed generation in distribution grids causes occasional voltage variations. The ICT infrastructure can provide the appropriate means for novel techniques to handle this kind of problems. The proposed algorithm utilizes a power flow model of the distribution grid and integrates the detection and the solution of the voltage constraint violation into a distributed double layered framework. The optimal solution of the related resource allocation problem involves the control of flexible microgenerators and loads, which can assist the grid by providing ancillary services for voltage control. The method is based on a gradient descent and a consensus algorithm for the distributed calculation of the Lagrangian multipliers. The proposed algorithm is tested in different scenarios in order to demonstrate its effectiveness.
