Measurement Design of Data Exchange for Distributed Multi-Utility Operation

چکیده
With power market deregulation, member companies cooperate to share one whole grid system and try to achieve their own economic goals. This paper focuses on how to improve the state estimation result of member companies or ISO by exchanging raw or estimated data with neighboring member companies/ISO. The concept of Bus Redundancy Descriptor (BRD) is developed based on critical measurement set. BRD and leverage points are used as criteria to evaluate the quality of measurement systems. Accordingly, based on BRD a heuristic algorithm for measurement design under distributed multi-utility operation is presented to search for possible beneficial data exchange schemes. Numerical results verify that every member companies including ISO benefit from mutual data exchange when some principles of design are carefully applied.

Model Predictive Control of Distributed Energy Resources with Predictive Set-Points for Grid-Connected Operation
This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...
متن کاملMulti-objective and Scalable Heuristic Algorithm for Workflow Task Scheduling in Utility Grids
To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...

Using Neural Networks and Genetic Algorithms for Modelling and Multi-objective Optimal Heat Exchange through a Tube Bank
In this study, by using a multi-objective optimization technique, the optimal design points of forced convective heat transfer in tubular arrangements were predicted upon the size, pitch and geometric configurations of a tube bank. In this way, the main concern of the study is focused on calculating the most favorable geometric characters which may gain to a maximum heat exchange as well as a m...
