Abstract
This paper introduces a new distributed algorithm for computing DC power flow with secure information exchange among participating areas. The algorithm is based on the principles of the Diakoptics approach to distributed power flow execution. Power flow is computed in multiple steps through a precisely defined information exchange protocol between the coordinator and the individual areas. In the conventional Diakoptics algorithm, areas exchange the information about their generation and load with the coordinator. Our algorithm redefines the exchange of information protocol so that areas do not need to reveal their internal generation and load but only their effects on the rest of the grid. In this way, proprietary information about the exact locations and values of generation and demand are protected and cannot be uniquely deciphered. We illustrate this algorithm and the corresponding information exchange protocol on the IEEE 14-bus system.
