Renewable energy power generation could increase the uncertainties of power system with intermittent and stochastic performance, which has significant effect on Available Transfer Capability (ATC). With the rapid development of renewable energy power generation technology as well as the gradual maturity of power market, it has become essential to research the effect specially. The wind generato...

In recent years, reliability, availability, and capacity have become critical issues in power plants industries. It is also becoming a challenge to meet the demand without the expansion of aged power plants. This paper presents availability analysis of the power generation systems in cogeneration plants situated in Kuwait. Furthermore, an overview of the current situation about Kuwait power pla...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

As renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. This paper presents unit commitment (UC) which takes into account the volatility of wind power generation. The UC problem is solved with the forecasted intermittent wind pow...

The ongoing transformation of the European energy system comes along with new challenges, notably increasing amounts of power generation from intermittent sources like wind and solar. How current objectives for emission reduction can be reached in the future and what the future power system will look like is, however, not fully clear. In particular, power plant investments in the long run and p...

The advent of power quality sensitive equipment has made the provision of good power quality a real challenge across the globe. With the increasing usage of sophisticated sensitive electronic equipment in industrial, residential and commercial sectors, it is important to protect them from any power quality disturbance in order to avoid equipment damage and malfunction leading to financial loss ...

In conventional power systems, frequency and voltage deviations are chosen as indexes for characterizing conventional power system security. While  in an autonomous micro grid with Electronically Interfaced Distributed Generation (EIDG), frequency and voltage deviations  against power and loads disturbances perfectly controlled by f-P and V-Q controller. Unlike conventional power syst...

Using results from parametric optimization, we derive for chance-constrained stochastic programs quantitative stability properties for locally optimal values and sets of local minimizers when the underlying probability distribution is subjected to perturbations in a metric space of probability measures. Emphasis is placed on verifiable sufficient conditions for the constraint-set mapping to ful...

The small number of some reactant molecules in biological systems formed by living cells can result in dynamical behavior which cannot be captured by traditional deterministic models. In such a problem, a more accurate simulation can be obtained with discrete stochastic simulation (Gillespie’s stochastic simulation algorithm – SSA). Many stochastic realizations are required to capture accurate ...
