Abstract:The inverter is a significant part in the single phase grid-connected inverter system. The design of control strategy for photovoltaic power generation system has a decisive role in the system. The fractional order λ PI controller is applied to the gridconnected inverter to improve the single phase photovoltaic grid-connected system performance, which is based on the integrated photovoltaic grid-connected inverter system in this paper. Three parameters of fractional order controller are optimized by Particle Swarm Optimization (PSO), and compared with the integer order PI controller. The results show that fractional order λ PI controller can effectively reduce the harmonic components, and obtain better control effect than the integer order PI controller.

“…4 (a) and (b) illustrate the dc-ac conversion for a PV or fuel cell system with a single-stage dc-ac converter or double-stage converter system using a dc-dc converter followed by a dc-ac converter. Normally the single-stage topology needs an overrated inverter and high dc output voltage from the PV panel or fuel cell stack, and features high efficiency while suffering from limited power capacity, compromised output quality and limited operation range [9]. The recently proposed Z source converter topology with embedded voltage boost function can be a good candidate for this single-stage conversion [10,11].…”

“…6. It is a popular topology for small wind turbine systems [9], where the front end ac-dc converter is usually a diode rectifier bridge. A similar topology with three-phase grid interfacing inverter can be used for larger wind turbine systems, where a synchronous wind turbine generator through a three-phase diode rectifier (with ac-dc, dc-dc and dc-ac multi-stage conversion) can be more cost effective compared to an induction generator with a two-stage ac-dc and dc-ac power electronics interface using PWM rectifier and inverter [2].…”

-This paper discusses control and protection of power electronics interfaced distributed generation (DG) systems in a customer-driven microgrid (CDM). Particularly, the following topics will be addressed: microgrid system configurations and features, DG interfacing converter topologies and control, power flow control in grid-connected operation, islanding detection, autonomous islanding operation with load shedding and load demand sharing among DG units, and system/DG protection. Most of the above mentioned control and protection issues should be embedded into the DG interfacing converter control scheme. Some case study results are also shown in this paper to further illustrate the above mentioned issues.

Therefore, various numerical strategies are proposed to achieve a fast and accurate instantaneous single-phase output power calculation [12,13].…”

In order to enhance the stability of single-phase microgrid, virtual synchronous generator (VSG) control method is investigated in this paper. Its electromagnetic model and electromechanical model are established to illustrate the performance of VSG. Considering the 2nd fluctuation of fundamental-frequency in the output power, an instantaneous power calculation strategy is proposed based on the intrinsic frequency of single-phase VSG. Besides, a virtual power calculation method is presented to achieve islanded/grid-connected seamless transition. Stability analysis and comparison simulation results demonstrate the correctness of the presented power calculation method. At last, the effectiveness of the proposed approach is verified by comparison experiments of islanded/gridconnected operations in a 500 VA single-phase inverter.
