SMART SOP ARCHITECTURES AND POWER CONTROL MANAGEMENTS BETWEEN LIGHT DC RAILWAY AND LV DISTRIBUTION NETWORK

Abstract

This paper presents different architectures of smart soft open points to interface electrified DC railways and low voltage power distribution networks. Both networks have similar objectives of power losses reduction, preserve network stability even with a high penetration of renewable energy sources, and accommodate new energy sectors such as electric vehicles and energy storage systems. The proposed smart soft open points will enable a flexible inter-exchange of electrical power between the two networks in order to achieve these challenging objectives. Different power management control approaches are provided in this paper according to the traffic conditions on the railway network as well as the power and voltage conditions of the distribution network.
