Integration of Protection and Control for Railway Power Systems

The technology in intelligent terminals enables communication from the process level to the SCS, substation, SCADA/EMS, and the network levels. Any function and parameter can be programmed and changed remotely. Automatic sequences can be included on bay and substation levels utilising the SCS. In addition, with serial communication, binary inputs, and user programming, it is possible to adapt f...

Optimizing Trading Decisions for Hydro Storage Systems Using Approximate Dual Dynamic Programming

We propose a new approach to optimize operations of hydro storage systems with multiple connected reservoirs which participate in wholesale electricity markets. Our formulation integrates short-term intraday with long-term interday decisions. The intraday problem considers bidding decisions as well as storage operation during the day and is formulated as a stochastic program. The interday probl...

Dynamic Investment Strategies for Information Systems Development

This paper presents an analytical model for choosing optimal investment schedules for the development of new systems under various types of risk. Two modes of risk reduction are considered. In the first mode, risk is reduced by gathering information through prototype building or sequential development, where risky parameters are assumed to have unknown but fixed values. The second mode involves...

Automated Approach for Optimizing Dynamic Systems

The optimal design of nonlinear dynamic systems can be formulated as a multicriteria optimization problem. On the basis of a multi body system model integral type objective functions are defined evaluating the dynamic behavior of the system under consideration. Multicriteria optimization methods reduce the problem to nonlinear programming problems which can be solved with standard algorithms li...
