Equivalent Speed and Equivalent Power of the Wind Systems that Works at Variable Wind Speed
Soft Computing Applications, 2016Co-Authors: Florica Balog, M. Babescu, Horia Ciocarlie, Gheza-mihai ErdodiAbstract:This paper presents an analysis of the dynamics of the Wind systems that work at Variable Wind Speeds. This analysis is based on numerical simulations that use the motion equation. In this paper, usual mathematical models of both Wind turbine and permanent magnet synchronous generator are used. Based on the measurements of both Wind Speed and generator Speed, two basic sizes are defined, namely the equivalent Wind Speed and the optimum mechanical angular Speed. The optimum mechanical angular Speed is a function of equivalent Wind Speed. By analyzing the time variation of the generator rotation Speed, the area of optimum functioning can be determined and it is characterized by optimum mechanical angular Speed.

Control of Wind power systems imposing the current in the intermediate circuit of the converter at Variable Wind Speed
2015 9th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2015Co-Authors: Cristian-paul Chioncel, Gheza-mihai Erdodi, Doru-ionut Petrescu, Elisabeta Spunei, Nicoleta GillichAbstract:This paper presents a control method for a Wind turbine with a synchronous generator with permanent magnet (SGPM), to achieve optimal function in the optimal energy field at Variable Wind Speed. The Wind Speed and the angular Speed of the SGPM impose the value of the generator load in the optimal energy area. Based on energy balances, done with Speed and power measurements, the generator load is determined so that the system can be brought into the optimal energy area. The operation at maximum power of a Wind turbine (WT) is analyzed by modifying the generators load, under the terms of a significant Wind Speed variation in time. The coordinates of the maximum power point (MPP) change in time being determined by the instantaneous values of the Wind Speed and the mechanical inertia, not in every case the Wind turbine can be brought, in a timely manner, in the MPP area. The rapidity of the Wind Speed variation in time as well as the inertial value, are two fundamental elements upon which the operation in MPP depends. Prescribing the value of the DC current, Icc, from the intermediate converter circuit, a simple and useful control of the Wind turbine system can be achieved. The control method that allows the WT to function in the optimal energy area is based on knowing the value of Icc, which is determinate from Wind Speed and the angular mechanical velocity (AMV).

Wind system with storage in electrical accumulators
2015 9th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2015Co-Authors: Sorin Musuroi, Gheza-mihai Erdodi, Ciprian Sorandaru, Doru-ionut PetrescuAbstract:The aim of this paper is to obtain the energy stored in the electric accumulators (EA), for a Wind system operating at a time-Variable Wind Speed. Mechanical energy captured by the Wind turbine (VT) is converted into electric energy by permanent magnet synchronous generator, PMSG. The synchronous generator provides energy into an electric accumulator, by using a rectifier, in two ways: uncontrolled rectifier and controlled rectifier and adjusted load. The simulations performed in this paper can highlight the differences between the two situations.

Q-Learning based Maximum Power Extraction for Wind Energy Conversion System with Variable Wind Speed
IEEE Transactions on Energy Conversion, 1Co-Authors: Ashish Kushwaha, Madan Gopal, Bhim SinghAbstract:This paper presents an intelligent Wind Speed sensor less maximum power point tracking (MPPT) method for a Variable Speed Wind energy conversion system (VS-WECS) based on a Q-Learning algorithm. The Q-Learning algorithm consists of Q-values for each state action pair which is updated using reward and learning rate. Inputs to define these states are electrical power received by grid and rotational Speed of the generator. In this paper, Q-Learning is equipped with peak detection technique, which drives the system towards peak power even if learning is incomplete which makes the real time tracking faster. To make the learning uniform, each state has its separate learning parameter instead of common learning parameter for all states as is the case in conventional Q-Learning. Therefore, if half learned system is running at peak point, it does not affect the learning of unvisited states. Also, Wind Speed change detection is combined with proposed algorithm which makes it eligible to work for varying Wind Speed conditions. In addition, the information of Wind turbine characteristics and Wind Speed measurement is not needed. The algorithm is verified through simulations and experimentation and also compared with perturbation and observation (P&O) algorithm.
