“…The main idea is to ensure that the harmonic voltage level at each bus remains no higher than the planning level. To ensure that the allocation is equitable in some sense, allocated harmonic emission level should be an increasing function of load magnitude [5]. The basic information is the forecasts of power flows taking account of the system evolution in the future [3].…”

“…It was published in 1981 to provide direction on dealing with harmonics introduced by static power converters and other nonlinear loads [5]. A review was started in 1984, being published at 1992 incorporating the evolving understanding of the effect of static power converters and other nonlinear loads on electric power systems [1].…”

Abstract. For the connection of wind power plants into the public grid there are power quality procedures and limits that need to be complied with. The direct aim of those is to ensure a suitable power quality in the grid, but to ultimate aim is to ensure a high probability of electromagnetic compatibility. Each country has different requirements and standards, and with this, different procedures. In this paper, an overview of these methods will be given, together with some of the advantages and disadvantages. Furthermore, a review of the modifications regarding the latest versions of IEEE 519-1992 and IEC 61000-3-6 will be presented.

“…According to [13,14], the first control step is to designate the sliding surface, then the control rule is designed, so that the system state can be attracted to the sliding surface and it will not deviate from the sliding surface. The system at MPP must satisfy BP m BV m " 0, Equation (19) can be obtained [15]:…”

“…It can also be observed from Figure 12b that the harmonic component of the ESMC proposed in this paper is lower than that for both P&O and ESC. In this paper, the THD is also simulated by PSIM [19]. Table 3 shows the THD results for different speeds of the three control methods.…”

Maximum Power Point Tracking and Harmonic Reducing Control Method for Generator-Based Exercise Equipment

2016

This study uses a sliding mode control (SMC) in a generator-based exercise equipment (GBEE) with nonlinear P-V characteristic curves. A P-V characteristics curve can be influenced by varying the pedaling speed of the generator. The traditional maximum power point tracking (MPPT) control method is used with perturb and observe algorithms (P&O), extremum seeking control (ESC), etc. However, these control methods are not robust enough for control. SMC is created by two pattern methods for robustness control, approaching and sliding conditions. However, SMC allows infinite high-frequency switching of the sign function. If the sign function is used to switch the converter, it will cause the converter and switch life to be cut short, and also to form high frequency noise. Therefore, this study proposes an extension theory for an intelligent control method that will effectively improve conversion efficiency and responsiveness. This study compares generator input current waveforms for fast Fourier transform (FFT) for three different control methods. Finally, using simulation validates the stability and FFT analysis with power simulation (PSIM) software. The results of upgrading overall efficiency are about a 5% increase in efficiency and a faster response speed of about 0.5 s. The amount of generator input current harmonic is greatly reduced.
