“…transient response speed and transient response; during these processes, no interaction with voltage occurs, simplifying the removal of selected harmonics; and it does not require memory for performing these processes. The superiority of the SRP method with respect to other controlling methods is summarized in Table 2 [20,21].…”

Recent developments in power electronics have increased the usage of nonlinear loads in energy systems.With increases in the usage of semiconductor-sourced nonlinear loads, the adverse effects of harmonics-sensitive loads (e.g., protection control circuits and circuit breakers) have also increased. Generally, the negative effects of harmonics in power systems include the following: increased power losses; motor, generator, and transformer overheating; faulty operation of measurement and protection systems; lifetime shortening of electrical components; and parallel and series resonance problems. Therefore, harmonics has become a serious problem in current power electronics systems. However, harmonics can be reduced, particularly through drainage using filters. In this study, some power losses were detected in different facilities in the city of Van, Turkey, on the basis of the variable measurements (e.g., instantaneous electrical values, harmonics, flow, and voltage waveforms) obtained using ZERA MT 310 power analyzers. The harmonics causing these power losses were examined. Some simulation results for active filters were evaluated, and the overall effects of the harmonics are discussed. Shunt active power filter (SAPF) simulation was conducted using Simplorer 6.0, which is known to produce successful results in power electronics simulation applications. SAPF simulation requires the use of measurement points. This utilization of SAPF simulation has demonstrated that voltage drop and power loss in power distribution systems can be reduced. However, it was found that owing to their structure, semiconductor components produce harmonics and consume power.

“…The harmonics present in power systems are those of order 6 ± 1 ∈ ℤ), which turn into 6 ∈ ℤ) when changing the reference frame from stationary (abc or αβ) to synchronous (dq). This allows halving the number of resonant controllers needed to implement the current controller [14]. Therefore, since the 5th (negative sequence) and 7th (positive sequence) harmonics are usually present in the grid, the current control scheme of Figure 9 has been used to obtain the simulation results.…”

Abstract:The presence of an unbalanced voltage at the point of common coupling (PCC) results in the appearance of a negative sequence current component that deteriorates the control performance. Static synchronous compensators (STATCOMs) are well-known to be a power application capable of carrying out the regulation of the PCC voltage in distribution lines that can suffer from grid disturbances. This article proposes a novel PCC voltage controller in synchronous reference frame to compensate an unbalanced PCC voltage by means of a STATCOM, allowing an independent control of both positive and negative voltage sequences. Several works have been proposed in this line but they were not able to compensate an unbalance in the PCC voltage. Furthermore, this controller includes aspects as antiwindup and droop control to improve the control system performance.

“…It presents a clear physical meaning and accurate harmonic extraction results, and many other developed forms have been inspired by it [23]- [26] . However, cost computation is inevitable during Park transforms from the stationary frame to the synchronous rotation frame (SRF), especially when multiple harmonics are concerned.…”

For a single-phase active power filter (APF), designing a more efficient algorithm to guarantee accurate and fast harmonics extraction with a lower computing cost is still a meaningful topic. The common idea still employs a IRPT-based Park transform, which was originally designed for 3-phase applications. Therefore, an additional virtual signal generation (VSG) link is necessary when it is used in the single-phase condition. This method, with virtual signal generation and transform, is obviously not the most efficient one. Regarding this problem, this paper proposes a novel harmonics extraction algorithm to further improve efficiency. The new algorithm is based on the principle of trigonometric orthogonal functions (TOF), and its mathematical principle and physical meaning are introduced in detail. Its implementation and superiority in terms of computation efficiency are analyzed by comparing it with conventional methods. Finally, its effectiveness is well validated through detailed simulations and laboratory experiments.
