Nodal prices determination with wind integration for radial distribution system

Abstract

With competitive electricity market operation, open access to the transmission and distribution network is essential for transparent and efficient market operation. Like transmission pricing, distribution network pricing must also be transparent and must include tile variations based on the change in the operating state of the system, integration of renewable sources and must be real time. In this paper, a distribution system nodal pricing scheme is proposed for radial distribution system with integration of wind power in the system. The main objective of the paper is: (i) an optimal power flow based approach for determination of nodal prices for distribution system, (ii) impact of wind generation on nodal prices. The results have been obtained for IEEE 33 bus test system.
