This paper provides an overview of the islanding potential of solar photovoltaic (PV) inverters.

Design of immittance inverters and phase inverters with non-foster elements

2018 22nd International Microwave and Radar Conference (MIKON), 2018

Non-Foster negative capacitances and inductances are attractive elements that allow designing broadband microwave devices and providing extra design flexibility due to their specific frequency dependence of reactance. Since this frequency dependence cannot be obtained from passive circuits according to Foster's theorem, the active circuits known as negative impedance converters (NICs) are used to realize non-Foster elements. Characteristics of NIC circuits ...

  • Parallel operated inverters as a multilevel case

    This paper considers the classification of parallel operation of voltage source inverters in the context of multilevel inverter systems. The similarity between the unfiltered outputs of multistage inverters, diode-clamped inverters and flying-capacitor inverters on the one hand and the unfiltered output of the parallel inverters scheme proposed in this paper on the other hand is discussed. It is proposed that one may use multilevel inverters as a backdrop in which to discuss the parallel operation of voltage source inverters. By unifying the areas of research for parallel operated and multilevel inverters, it is suggested that the parallel scheme may be employed more in the near future.

  • Assessing solar PV inverters' anti-islanding protection

    This paper provides an overview of the islanding potential of solar photovoltaic (PV) inverters. Solar PV inverters are typically known to have very effective protection mechanisms, but concerns have been raised as to whether or not they could maintain an island if load and generation were closely matched and/or if there were additional sources of distributed generation on a circuit. Also provided are the test results of multiple solar PV inverters operating in parallel during a variety of islanding scenarios. Additional tests included evaluating German inverters to investigate whether or not advanced features (such as volt/VAR controls and low-voltage ride- through) and load matching can compromise the solar PV inverters' anti- islanding protection. The testing was performed in Southern California Edison's Distributed Energy Resources Laboratory in Westminster, California. The results detailed here provide information that can be used to develop national standards for advanced features on solar PV inverters. Residential U.S. inverters have a nominal voltage of 240 V line to line, and German inverters are 230 V line to neutral. The frequency of the German inverters was adjusted to 60 Hz to reflect American standard practices.

  • Design of immittance inverters and phase inverters with non-foster elements

    Non-Foster negative capacitances and inductances are attractive elements that allow designing broadband microwave devices and providing extra design flexibility due to their specific frequency dependence of reactance. Since this frequency dependence cannot be obtained from passive circuits according to Foster's theorem, the active circuits known as negative impedance converters (NICs) are used to realize non-Foster elements. Characteristics of NIC circuits depend strongly on parameters of active components used. We investigated how characteristics of a NIC to realize a negative capacitance for the GHz frequency range depend on the transistor critical frequency. It is demonstrated in the paper that a proper selection of transistors makes it possible to realize negative capacitances with a low variation over a wide frequency band. Possibilities of using the realized negative capacitance to design reactance networks of immittance inverters and broadband phase inverters were then investigated. The im-mittance inverters with non-Foster elements can be employed for filter design with an advantage of no need for subtraction of negative capacitances. The broadband phase inverter which is a cascade of two identical immittance inverters can be used to design a broadband 180° switchable-channel phase shifter with a low phase shift error.

  • Application of parallel connected NPC-PWM inverters with multilevel modulation for AC motor drive

    The neutral point clamped (NPC)-PWM inverters have been put into practical use for large capacity AC motor drives, because of their many advantages. With the increase in use, still larger capacity inverters are also expected. In this paper, a parallel connected NPC-PWM inverter is applied for AC motor drive. The conventional modulation techniques are extended to improve the inverter characteristics. To determine an optimum modulation for controlling the parallel connected NPC-PWM inverter, various modulation techniques are devised and discussed, whose results are verified by experiment.

  • Pulse-width modulation of Z-source inverters

    Z-Source inverters have recently been proposed as an alternative power conversion concept as they have both voltage buck and boost capabilities. These inverters use a unique impedance network, coupled between the power source and converter circuit, to provide both voltage buck and boost properties, which cannot be achieved with conventional voltage-source and current-source inverters. To facilitate understanding of Z-source inverter modulation, this paper presents a detailed analysis, showing how various conventional pulse-width modulation strategies can be modified to switch a voltage-type Z-source inverter either continuously or discontinuously, while retaining all the unique harmonic performance features of these conventional modulation strategies. This paper starts by analyzing the modulation requirements of a single-phase H-bridge Z-source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase- leg Z-source inverters, with carrier-based implementation reference equations derived for all the inverters. The theoretical and modulation concepts presented have been verified both in simulation and experimentally.

  • Control of Inverters Via a Virtual Capacitor to Achieve Capacitive Output Impedance

    Mainstream inverters have inductive output impedance at low frequencies (such inverters are called L-inverters). In this paper, a control strategy is proposed to make the output impedance of an inverter capacitive at low frequencies (such inverters are called C-inverters). The proposed control strategy involves the feedback of the inductor current through an integrator, which is actually the impedance of a virtual capacitor. The gain of the integrator or the virtual capacitance is first selected to guarantee the stability of the current feedback loop and then optimized to minimize the total harmonic distortion (THD) of the output voltage. Moreover, some guidelines are developed to facilitate the selection of the filter components for C-inverters. Simulation and experimental results are provided to demonstrate the feasibility and excellent performance of C-inverters, with the filter parameters of the test rig selected according to the guidelines developed. It is shown that, with the same hardware, the lowest voltage THD is obtained when the inverter is designed to be a C-inverter. A by product of this study is that, as long as the current ripples are kept within the desired range, the filter inductor should be chosen as small as possible in order to reduce voltage harmonics. This helps reduce the size, weight, and volume of the inductor and improve the power density of the inverter.

  • A Brief Study of Solar Home Inverters

    In every field of human development, electricity usage is increasing promptly. Utilization of solar energy is a way to meet the energy demand. The solar inverter is one such device, which makes the solar energy to usable form. In this paper, three major classifications of inverters are presented. The voltage source and current source inverters, stand-alone and grid-connected inverters and, square, modified square and sine wave inverters come under the classification. An open loop strategy is considered for the MATLAB Simulation of the three main types of PWM inverters available in the market. A brief description of PV array, charge controller and battery is also presented in this paper.

  • Output Impedance Modeling and Stability Prediction of Three-Phase Paralleled Inverters With Master–Slave Sharing Scheme Based on Terminal Characteristics of Individual Inverters

    Paralleled inverters are widely employed as the power source in the AC distributed power system, whose output impedance and stability status are required in the impedance-based stability analysis of the whole system. This paper presents an output impedance model as well as a stability prediction method for three-phase paralleled inverters with master-slave sharing scheme. While the output impedance of three-phase paralleled inverters is generally modeled under synchronous reference frame (SRF), the terminal characteristics of individual inverters operating standalone are innovatively adopted in the proposed output impedance model, with no need for knowledge about inner parameters of the inverters. Furthermore, the stability criterion is derived with this model according to the generalized Nyquist criterion, where the stability of paralleled inverters can be predicted by investigating characteristic loci of two return ratios. Meanwhile, the terminal characteristics of individual inverters controlled under SRF is comprehensively modeled. Finally, the proposed output impedance model and stability criterion were experimentally verified.

  • Harmonic reduction in the parallel arrangements of grid-connected voltage source inverters

    The elimination of low order harmonics in grid-connected renewable-energy inverter systems is desirable both from the point of view of grid health as well as efficient inverter operation. In this paper, one inverter (called reference inverter) employs pulse width modulation (PWM) with conventional selective harmonic elimination (SHE) to remove the 5<sup>th</sup> and 7<sup>th</sup> harmonics. By adjusting a delay in the gating signals to four inverters for example, it is possible also eliminate other higher significant harmonics, namely the 11<sup>th</sup> and 13<sup>th</sup> harmonics, without any increase in the switching frequency. This approach may be useful for high power grid-connected inverter systems supplied by alternative energy sources where switching losses may become prohibitive if the switching frequency is too high. Two and four parallel inverters systems are investigated and simulated in PSPICE and MATLAB.

  • VAr support from solar PV inverters

    This paper provides an overview of the need and applications for solar photovoltaic (PV) inverters with Volt/VAr feature to provide grid support during steady state and/or system events. This paper will also provide test results from residential and commercial PV inverters designed to operate according to German standards, which now allows voltage support. The residential inverters output voltage was 230 volts line-to-ground and the commercial was 400 volts line-line, reflecting the typical German residential and commercial voltage configurations respectively. The inverters frequency was adjusted to 60 Hz in order to reflect American standard practices. The testing was performed in Southern California Edison's (SCE) Distributed Energy Resources (DER) Laboratory in Westminster, California. The primary reason for the testing is to explore features not presently required by U.S. standards. The results detailed here provide information that can be used to develop national standards for voltage regulation features on PV inverters.
