An EU Future Internet Engineering project currently underway in Poland defines three parallel internets (PIs). The emerging IIP system (IIPS, abbreviating the project’s Polish name), has a four-level architecture, with level 2 responsible for creation of virtual resources of the PIs. This paper proposes a three-tier security architecture to address level 2 threats of unauthorised traffic inject...

in this paper a comprehensive approach is presented to improve power swings damping based on direct lyapunov method. the approach combines superconducting magnetic energy storage (smes) system with static synchronous compensator (statcom). considering the energy absorption/injection ability of smes, in transient states the combination exchanges both active and reactive powers with power system....

Grid impedance estimation is used in many power system applications such as grid connected renewable energy systems and power quality analysis of smart grids. The grid impedance estimation techniques based on signal injection uses Ohm’s law for the estimation. In these methods, one or several signal(s) is (are) injected to Point of Common Coupling (PCC). Then the current through and voltage of ...

In this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. The system will be connected inparallel between the grid and load. The proposed system supplies all load power consumption(including active po...

Accurate short-term wind power forecasting with quantification of the associated uncertainty is crucial for the management of energy systems including wind power generation. On top of the inherent uncertainty in wind speed, it is necessary to account also for the uncertainty in the relationship between wind speed and the corresponding power production, typically described by a power curve whose...

Despite the significant therapeutic advances achieved with proteasome inhibitors (PIs) such as bortezomib and carfilzomib in prolonging the survival of patients with multiple myeloma, the development of drug resistance, peripheral neuropathy, and pharmacokinetic limitations continue to pose major challenges when using these compounds. Ixazomib is a second-generation PI with improved activity ov...

Reliable and accurate ultra-short-term prediction of wind power is vital for the operation optimization systems. However, volatility intermittence pose uncertainties to traditional point prediction, resulting in an increased risk system operation. To represent uncertainty power, this paper proposes a new method interval based on graph neural network (GNN) improved bootstrap technique. Specifica...

Accurate regional wind power prediction plays an important role in the security and reliability of systems. For performance improvement very short-term intervals (PIs), a novel probabilistic method based on composite conditional nonlinear quantile regression (CCNQR) is proposed. First, hierarchical clustering weighted multivariate time series motifs (WMTSM) studied to consider static difference...

an industrial gas turbine has the characteristic of decreasing output power on hot summer days while electricity demand peaks. steam injection in gas turbines has been used for many years to prevent the loss of performance of gas turbines caused by high ambient temperature. vodoley system is a closed steam injection gas turbine cycle (csigtc), which is known as a self-sufficient in steam produc...
