PROJECT TITLE :

Master–Slave-Splitting Based Distributed Global Power Flow Method for Integrated Transmission and Distribution Analysis

ABSTRACT:

With the recent rapid development of smart grid technology, the distribution grids become a lot of active, and therefore the interaction between transmission and distribution grids becomes additional significant. But, in traditional power flow calculations, transmission and distribution grids are separated, which is not appropriate for such future smart grids. To achieve a global unified power flow answer to support an integrated analysis for both transmission and distribution grids, we propose a international power flow (GPF) methodology that considers transmission and distribution grids as a full during this paper. We construct GPF equations, and develop a master-slave-splitting (MSS) iterative technique with convergence guarantee to alleviate boundary mismatches between the transmission and distribution grids. In our technique, the GPF downside is split into a transmission power flow and a number of distribution power flow sub-problems, which supports on-line geographically distributed computation. Each sub-downside can be solved employing a totally different power flow algorithm to capture the different options of transmission and distribution grids. An equivalent technique is proposed to enhance the convergence of the MSS-primarily based GPF calculation for distribution grids that include loops. Numerical simulations validate the effectiveness of the proposed technique, in explicit when the distribution grid has loops or distributed generators.
