Train Power Demand Control Using Decentralized and Parallel Control Scheme

Abstract

It is important for railway companies to reduce the power consumption of substations in order to reduce the contract power cost and facilities. This study proposes a decentralized control system for controlling the train power demand. Each train calculates its own power allocation independently and in parallel using the information broadcasted by the substations in this control scheme. This control system is very advantageous from the view point of communication load, plug & play' and capital investment because it does not need a server. This work investigates the effect of train power control using the decentralized control scheme via simple and precise numerical simulations' which demonstrate that several trains run on the railroad and are powered by a substation.

Ancillary services and electric vehicles: An overview from charging clusters and chargers technology perspectives

“…The control approaches of smart chargers can be divided into centralized, decentralized, and distributed. Table 3 merges the findings from authors of [5, [185][186][187][188][189] regarding advantages and drawbacks of each control approach. So far, smart chargers have followed in a large majority the centralized control approach, mainly due to simplicity of implementation and a more mature architecture [190].…”

Autonomously Distributed Control of Electric Vehicle Chargers for Grid Services

“…On the contrary, the decentralized architecture requires less communication and computation capabilities [15], [16] and diverts data privacy challenges. Moreover, the one-way communication has the potential of implementing plug & play protocols and simplify user interaction [17].…”
