Access Control Mechanism

Trust management is a distributed access control mechanism for open, large-scale network. SPKI/SDSI and RT0 are typical trust management systems. This paper compares the different crendentials in those systems essentially, and the result shows that although RT0 crendentials are relatively simple, they are expressively eauivalent to SPKI/SDSI crendentials.

Optimal Implementation

This paper aims to provide the smart grid research community with an open and accessible general mathematical framework to develop and implement optimal flexibility mechanisms in large-scale network applications. The motivation of this paper is twofold. On the one hand, flexibility mechanisms are currently a hot topic of research, which is aimed to mitigate variation and uncertainty of electricity demand and supply in decentralised grids with a high aggregated share of renewables. On the other hand, a large part of such related research is performed by heuristic methods, which are generally inefficient (such methods do not guarantee optimality) and difficult to extrapolate for different use cases. Alternatively, this paper presents an MPC-based (Model Predictive Control) framework explicitly including a generic flexibility mechanism which is easy to particularise to specific strategies such as Demand Response, Flexible Production and Energy Efficiency Services. The proposed framework is benchmarked with other non-optimal control configurations to better show the advantages it provides. The work of this paper is completed by the implementation of a generic use case which aims to further clarify the use of the framework and thus, to ease its adoption by other researchers in their specific flexibility mechanisms applications.

Data Collection Technique

In Large-scale network applications, transmission data collection is the basis for audit, analysis and evaluation of systems and users. Transmission data collection can be carried out either on the link line or on the host where the network application is running. Collecting at different locations, the types of data acquired are different, thus need different processing. This paper first analyzes the different transmission data collection methods, their advantages as well as disadvantages. Then analyzes the structure of those network applications that are basing on transmission dynamic linked library, promotes the intermediate DLL method. Finally through an example it shows how to define the intermediate DLL to collect transferred data on application layer without affecting the original system function.
