This paper reviews potential operational challenges facing hybrid power plants, particularly solar photovoltaic (PV) plus battery energy storage systems (BESS). Real-world operation has witnessed many challenges, e.g., overvoltage at fault recovery, oscillations during PV ramping up, large phase angle change faults, etc. while focusing on those caused by plant-level control and inverter-level c...

The implementation of maximum power point tracking (MPPT) schemes by the ripple correlation control (RCC) algorithm is presented in this paper. A reference is made to single-phase single-stage multilevel photovoltaic (PV) generation systems, when the inverter input variables (PV voltage and PV current) have multiple low-frequency (ripple) harmonics. The harmonic analysis is carried out with ref...

In this paper, a control method for inverter air conditioner is presented, which is to use evaporating pressure as middle-target via fuzzy method. It is a method to control in cascade stage. Simulation results of performance of the control method, comparing with a traditional fuzzy method, were obtained.

We know that, the inverters are broadly classified as two level inverters and multilevel inverters. This conventional inverters have many limitations at high power and high voltage applications. However, the multilevel inverter becomes popular for high power and high voltage applications due to their increased number of levels at the output. As number of levels increases, the harmonics are redu...

The increasing penetration of inverter-based distributed generations (DGs) significantly affects the fault characteristics of distribution networks. Fault analysis is a keystone for suitable protection scheme design. This paper presents the modelling methodology for distribution networks with inverter-based DGs and performs fault simulation based on the model. Firstly, a single inverter-based D...

This paper presents the novel multilevel inverter fed control structure for induction motor based Direct Torque Control (DTC) strategy using a seven-level Multi Point Clamped (MPC) Voltage Source Inverter (VSI) is presented. It is shown that the multilevel topology presents enough degrees of freedom to control both electromagnetic torque and stator flux with very low ripple and high dynamics on...

This paper presents a Modified control method for Space Vector Modulated (SVM) Z Source inverters. Proposed algorithm provides a modified voltage vector with single stage controller having one degree of freedom wherein traditional controllers have two degrees of freedom. Through this method of control, the full utilization of the dc link input voltage and keeping the lowest voltage stress acros...
