Resource allocation in High Performance Computing (HPC) settings is still not easy for end-users due to the wide variety of application and environment configuration options. Users have difficulties to estimate the number of processors and amount of memory required by their jobs, select the queue and partition, and estimate when job output will be available to plan for next experiments. Apart from...
This paper proposes a new method for determining the LDC (Load Drop Compensator) parameters of LRT (Load Ratio Transformer) and SVR (Step Voltage Regulator). Since the voltage control effect of LRT and SVR depends on the LDC parameter, the proper parameters should be chosen in order to control voltage within proper range. When the photovoltaic generation system is installed in the distribution system,...
A model has been developed for the simulation of Central-European electricity market forecast for the next 5-10-15 years. This simulator simulates the trade flows that are not equal with the physical flows. In this paper some scenarios are introduced: border capacity change, border cross price change, load and generation capacity changes. The simulation is capable to calculate the long term prices...
There has been a significant production of load forecasting models over the last 5 years. These models present a wide variety of techniques, most of them using novel artificial intelligence approaches. Load forecasting is a complex matter and it is the result of several processes that, depending on the database, may be of more or less importance. However, most models focus their attention only on...
The aim of this paper is to present how the Day Ahead Congestion Forecast (DACF) procedure can be facilitated and automated by a specially developed software solution. DACF is a regular procedure for power flow forecast in the European Interconnected network, performed on daily basis (today for tomorrow). The emphasis in this paper is on the first step of the procedure which is creation of regional...
The ability to perform lot arrival forecast at work center level is a key requirement for pro-active FAB operation management. Visibility to this information enables preemptive resource allocation and bottleneck management. Today, the work center lot arrival forecast is achieved through the use of short term simulation technique in Infineon Dresden. High fidelity simulation model that includes detailed...
Power-marketing system is one of the most important core operations in power supply enterprises. This paper mainly introduces research and design of the prediction subsystem of power-marketing system and gives the structure frame and characters of this system. It also describes the whole structure of the decision-making prediction system and the main prediction models used in the system. Finally,...
The size of unified modeling language (UML) models used in practice is very large and ranges up to hundreds and thousands of classes. Querying of these models is used to support their quality assessment by information filtering and aggregating. For both, human cognition and automated analysis, there is a need for fast querying. In this context performance of model queries becomes an important issue...
