Voltage controlled stand-alone microhydro induction generator system
Nigim, K.A. - In: International Journal of Global Energy Issues 24 (2005) 1/2, pp. 100-111
The paper discusses simulated control cases of the wound rotor self-excited induction generator WRSEIG. The generator external controller is designed to regulate the output voltage and frequency for constant or variable speed operation of the prime mover and has the inherent capability of...

Reactive power control of wind-diesel-micro-hydro hybrid power systems using matlab/simulink
Bansal, R.C.; Bhatti, T.S.; Kothari, D.P.; Bhat, S. - In: International Journal of Global Energy Issues 24 (2005) 1/2, pp. 86-99
This paper presents reactive power control of isolated wind-diesel-micro-hydro hybrid power system for realistic load disturbance using matlab/simulink. The mathematical model of the system based on matlab/simulink is developed. Reactive power control performance is compared using three...

Control of dynamic effects in small hydro with long hydraulic circuits
Ramos, Helena; Almeida, A. Betamio De - In: International Journal of Global Energy Issues 24 (2005) 1/2, pp. 47-58
Lab tests in a long hydraulic circuit were developed to analyse hydrotransients induced by waterhammer effects under runaway conditions. The definition of suitable design criteria in hydraulic systems is of utmost importance and has become a priority for good design implementation. The dynamic...

Finite sample correction factors for panel cointegration tests
Hlouskova, Jaroslava; Wagner, Martin - 2009
In this paper we present finite T mean and variance correction factors and corresponding response surface regressions for the panel cointegration tests presented in Pedroni (1999, 2004), Westerlund (2005), Larsson et al. (2001), and Breitung (2005). For the single equation tests we consider up...

Reproducible Econometric Simulations
Kleiber, Christian; Zeileis, Achim - 2011
Reproducibility of economic research has attracted considerable attention in recent years. So far, the discussion has focused on reproducibility of empirical analyses. This paper addresses a further aspect of reproducibility, the reproducibility of computational experiments. We examine the...

Standard and Shuffled Halton Sequences in a Mixed Logit Model
Staus, Alexander - 2008
. Simulation methods have been developed to approximate a solution for these integrals. This paper describes the Standard Halton … sequence and a modification of it, the Shuffled Halton sequence. Both are simulation methods which can reduce computational … effort compared to a random sequence. We compare the simulation methods in their coverage of the multi-dimensional area and …

Autonomously Interacting Banks
Lengwiler, Yvan; Maringer, Dietmar - 2011
The great financial turmoil that started 2007 has brought bank regulation back into the political debate. There is talk about imposing new regulations on banks and other financial intermediaries. Yet, we are not convinced that it is completely understood how the existing regulation affects...

Firms formation and growth in the model with heterogeneous agents and monitoring
Marko, Peter; Švarc, Petr - 2008
In this article we extend the agent-based model of firms' formation and growth proposed in [4]. In [4] the firms' creation, expansion or contraction results from the interaction of heterogeneous utility maximizers. While the original model was able to replicate the power law distribution in the...

Technology adoption and herding behavior in complex social networks
Švarcová, Natalie; Švarc, Petr - 2008
Using a simple computational model, we study consequences of herding behavior in population of agents connected in networks with different topologies: random networks, small-world networks and scale-free networks. Agents sequentially choose between two technologies using very simple rules based...
