INTRODUCTION Now a days the power consumption is more compared to the available power and the pollution is also increasing. So, one of the solutions to overcome the above mentioned two disadvantages is producing the power with the renewable energy sources which are unlimited and non-pollutant. Among the available renewable energy sources, wind and solar sources [1] have number of advantages like unlimited, clean. Using wind as a source there have been number of wind turbines like Horizontal axis wind turbine, vertical axis wind turbine, Darrius wind turbine but the disadvantages with these wind turbines is high investment, noise, fatal to birds, higher wind speed requirement and no availability of wind all the times. So solar can be used for power generation but even it has disadvantage that it is not available at night times and no power generation. So, using of single renewable source at a time may not meet the load requirement and so by combining these sources [2, 3] they can be effectively used which leads to hybrid system. Standalone Hybrid power generation system [4-6] produces electrical energy with the use of more than one source and if one is not available another source can be used +for running the load. Standalone Solar wind hybrid power generation system uses solar and wind as sources, but the conventional wind turbine has disadvantages like higher wind speed requirement, high investment, fatal to birds, noise. Bladeless wind turbine is an alternative solution of generating power with wind and getting rid of the disadvantages of conventional horizontal axis wind turbine and the basic principle behind the bladeless turbine is vortex induced vibrations [4]. Vortex vibrations are the vibrations that are induced with in a structure when wind is passed through it and producing oscillatory motion. These oscillations can be converted into electrical energy using devices like piezoelectric cells, crank and shaft mechanism, linear alternator but producing low energy, high maintenance and so transducer [7] can be opted for energy conversion. But the produced energy may not be sufficient for usage and so high gain step up DC-DC converter can be used for boosting the voltage up to the required value instead of using conventional boost converter. To reduce the filter requirements and to reduce total harmonic distortion of output energy three level inverter [8] can be used instead of conventional two-level inverter. The paper is organized as follows; the first section of the paper is dealing with the comparision of proposed bladeless hybrid system and conventional hybrid system, the second section of the paper is dealing with the mathematical modelling of proposed bladeless hybrid system and the third part discusses with controller for wind turbine and the fourth part deals with the software realization of proposed system, result and discussion of the proposed system and the fifth part deals with the conclusion. 2. PROPOSED BLADELESS WIND SOLAR HYBRID SYSTEM VS CONVENTIONAL HYBRID SYSTEM The proposed bladeless hybrid system which is shown in below Figure 1 works on the principle of vortex induced vibrations. It is an integrated system of bladeless wind turbine and solar panel in which the bladeless wind turbine consists of a tapered cylindrical mast made up of fiber glass or carbon fiber and a rod is pivoted into the mast which provides support to the mast. When wind passes over the mast, vortex vibrations are induced around the mast in which alternating forces are produced and the mast starts displacing. To make the mast to oscillate with continuous to and pro motions and to increase the oscillations of the mast, a spring has been attached at the bottom the turbine. These oscillations are converted to electrical energy by using electro-acoustic transducer and then to DC power by European Journal of Electrical Engineering Vol. 21, No. 3, June, 2019, pp. 327-332 Journal homepage: http://iieta.org/journals/ejee 327
