“…Similarly, the mechanical power P m * shown in (8) can be transformed to the function of slip s slip Figure 9a illustrates the mechanical power and air-gap power with respect to slip according to (11) and (13). As shown in the figure, there are three intersection points when the infinite voltage is 1.0 p.u., and only the middle operating point is unstable.…”

“…However, microgrids can be subjected to a high penetration level of induction motor loads, and the highly nonlinear IM loads dynamics may challenge the stability of microgrids [12]. Besides, although the newly installed wind turbines are connected to grid through power electronics and researches are mainly focus on novel control strategy of these machines [13,14], a certain number of Type 1 induction generators are still operating in conventional wind farms [15]. As a result, the dynamic behavior of induction machines has a significant impact on power system stability.…”

Power balance, including active and reactive power, between the system supply and the demand from induction motor loads is a potentially necessary condition for system stable operation. Motion of system states depends on the balancing of active and reactive powers. Therefore, this paper proposes an induction machine model in electromechanical timescale from a power balancing viewpoint, in which the induction motor load is modeled as a voltage vector driven by power balancing between the system supply and the demand from induction motor load, so as to describe the dynamic characteristics of induction motor loads in a physical way for power system dynamic analysis. Then a voltage magnitude-phase dynamic analysis with the proposed induction machine model is constructed. Based on the voltage magnitude-phase dynamic analysis, the characteristics of grid-connected induction motor loads are explored, and the instability mechanisms of grid-connected induction motor loads induced by a large disturbance are discussed. It is shown that the dynamic behavior of grid-connected induction motor loads can be described as the dynamic process of the terminal voltage vector driven by coupled active and reactive power balancing in different timescales. In this way, the dynamic behavior of induction motor loads in terms of voltage magnitude-phase dynamics and its physical characteristics are clearly illustrated. Time-domain simulation results are presented to validate the above analyses.

“…In [10] Advanced HCS is proposed which stores the data given by HCS algorithm in an intelligent memory and uses these data to find the reference speed instead of searching again and this algorithm is generically called Search-Remember-Reuse algorithm. In [18] P & O is used for MPPT for WECS supplying DC micro-grid. The Optimum Relation Based (ORB) algorithm uses relation between system parameters to estimate the reference speed.…”

Abstract---This paper deals with modelling of Permanent Magnet Synchronous Generator (PMSG) based Wind Energy Conversion System (WECS) for extracting maximum power from the wind energy using Maximum Power Point Tracking (MPPT) algorithm. This design implements a variable speed wind turbine so that it can be operated at maximum efficiency for all wind speeds within the cut-in and furling speed limit in contrast to the fixed speed wind turbines. This design uses AC-DC-AC topology. The converters use SVPWM to reduce THD (Total Harmonic Distortion). A hybrid MPPT algorithm is implemented using FLC (Fuzzy Logic Controller).Turbine, Generator and Drivetrain assembly is modelled using Two mass model-instead of lumping the inertia of the three masses-to study the dynamic response of the model as the MPPT algorithm changes the rotor speed according to wind speed variations.

“…Wind energy as an important type of the available renewable energies has been permanently attractive for man, and has been even utilized by some old devices such as windmills for centuries. A WECS essentially consists of a wind turbine and an electric generator [2], although for an efficient WECS supplied to a DC load, an AC/DC converter including a three-phase rectifier, and a MPPT controller are also necessary [3].…”
