An energy system is a structure of network consisting of energy sources, storage, transmission, distribution, and consumption of energy. The basic primary use of energy is for transportation, heating, industrial and electricity sectors. These sectors are generally based on traditional fossil fuels. However, the issues, challenges and causes are evolving due to severe climatic conditions prevailing in the world, and it is important to use enormous amounts of renewable energy systems to ensure carbon negativity by encouraging clean and green energy replacing fossil fuels with solar, hydro and wind energy systems. Due to population growth, rapid rise in demand can be seen and to meet the demand, power generation must be correspondingly increased, and hence more renewable energy systems must be infused into the power grid to meet the rising demand for power generation. Over the past two decades, deregulation and transition towards the smart grid, leading to structural changes in the power grid, increased the complexity in the network. The power from injected renewable is intermittent in nature and hence it is unreliable. Due to this supply demand mismatch occurs leading to wide frequency oscillations in the system. However, owing to the complicated structure of the system, regulating the grid frequency is a major control problem and sometimes it may also give rise to power disruptions. Among all the renewable energy sources wind energy sources have more demand due to their availability. Presently, wind energy systems are integrated into the grid through DFIG and back-to-back converters. As these converters operate at low voltages, an additional edge of reducing capital cost including protective devices, cost of maintenance, total harmonic distortion can be achieved. The back-to-back converters comprise of two converters operating in rectifying and inverting modes respectively. In general, inverters are classified based on various characteristics like type of output, single-phase inverters (SPIs) and three phase inverters (TPIs), nature of input source, voltage source inverters (VSIs) and current source inverters (CSIs). The shunt capacitor at the input terminals reduces the dc ripple content particularly second harmonics which are prone to harm the source. This leads to a smoother dc voltage. Though solid-state power electronic switches, viz. IGBTs and MOSFETs have brought about significant merits in control complexity, they produce harmonics which are quite detrimental to the performance of the system. Harmonic voltages affect the power network and also the critical equipment in the vicinity of the harmonic source. This may result in erroneous operation of the sensitive loads. Hence, harmonic content must be reduced to an acceptable level and before designing a converter, one should consider standards of THD constraints. Nevertheless, completely eliminating harmonic currents from an electrical system is very challenging and difficult but can be reduced significantly using harmonic filters. Most power electronic converters generate distorted wave shape that can further be decomposed into integral multiples of fundamental component. They can be eliminated using multilevel inverters, by tuning the controller/adding the respective harmonic filters.
