The operation and the development of power system networks introduce new types stability problems. effect generation consumption on frequency can be described as a demand/generation imbalance resulting from sudden increase/decrease in demand and/or generation. This paper investigates impact loss transient behaviour grid frequency. A simplified model is proposed to examine change main parameters...

Large-scale deployment of Renewable Energy Sources (RES) has led to significant generation shares of variable RES in power systems worldwide. RES units, notably inverterconnected wind turbines and photovoltaics (PV) that as such do not provide rotational inertia, are effectively displacing conventional generators and their rotating machinery. The traditional assumption that grid inertia is suff...

-In haptic devices the problem of major concern is the inertia offered by the haptic device. When using it in unconstrained space, it should offer the least inertia. Depending on the interaction mechanism we are required to adapt different control algorithms to maintain transparency. This paper investigates force feedback method of inertia reduction and analyses its advantages over the feed for...

K hydropower station is a hydraulic engineering with the main task of power generation, which also typical low head, large discharge and long tail water conveyance system. The characteristics these-type stations are high inertia, amplitude surge chamber level fluctuation poor stability units. Therefore, due to control requirements stability, area horizontal section usually large, leads period r...

in this study, eutrophication was investigated in lake ontario to identify the interactions among effective drivers. the complexity of such phenomenon was modeled using a system dynamics approach based on a consideration of constant and variable stoichiometric ratios. the system dynamics approach is a powerful tool for developing object-oriented models to simulate complex phenomena that involve...

In this study, we introduced a simple method to determine the moment of inertia using a dynamometer. In order to evaluate the developed method, one male was required to test for his forearm including the hand on a dynamometer. In the process of finding moment of inertia, three different passive speeds, i.e. 240°/s, 270°/s, and 300°/s, were performed to confirm whether the calculated values at t...
