“…Where ∆ is the output of the d-axis PI current regulator and is the output of the q-axis PI current regulator. ∆ is multiplied by gain and added to the q-axis voltage equation * representing the part of the derivative term in the dynamic voltage equation given in Equation (3). Similarly, the ∆ terms in Equation ( 3) and Equation ( 4) also behave as the derivative representation given in Equation ( 1) and Equation (2) for achieving a better transient response in the sensorless operation.…”

The main aim of this paper is to provide electric power generation using a renewable and portable method in rural and geographically problematic areas where energy transmission is not possible. Electric power generation from wind with low-cost, efficient and portable smallscale wind turbine during natural disasters (earthquake, fire, flood, etc.) leading to catastrophic consequences (long electrical blackouts) and for individual low power applications is targeted. The control of gearless Permanent Magnet Synchronous Generator (PMSG) along with load side inverter control in this project are performed using a fullrating, bi-directional, two-level, back-to-back voltage source rectifier/inverter with total of eight switches for the variable speed wind turbine. Additionally, one of the major advantages and novelty of using MRAS rotor flux linkage and stator resistance estimator in this system is to correct changes in the flux and stator resistance values in the control system. Due to its simplicity and effectiveness, the load side control is achieved by using four switch grid side inverter. To observe the total system performance, a three-phase passive load is used at the inverter output. The low-pass LCL filter is designed and used in the load side to reduce current and voltage harmonics and increase stability and efficiency of the power network. The results of the overall system are validated with the real-time DSP system. It is proved with this paper that the inclusion of a simple, effective and economical position sensorless control in the generator side show that renewable wind energy system can be a viable distributed green energy solution for rural areas.
