“…The operation of the seven level inverter can be divided into the positive half cycle and the negative half cycle of the utility. For ease of analysis, the power electronic switches and diodes are assumed to be ideal, while the voltages of both capacitors C1 and [8]- [9] C2 in the capacitor selection circuit are constant and equal to Vdc/3 and 2Vdc/3, respectively. Since the output current of the solar power generation system will be controlled to be sinusoidal and in phase with the utility voltage, the output current of the seven-level inverter is also positive in the positive half cycle of the utility.…”

“…Active rectifiers are widely used in Smart Grids as interfaces for DC type generators, PV panels and bidirectional fast chargers for electric vehicles enabling V2G ancillary services [14,15,19,30,34,36,40,43,51]. Figure 5.28 shows schematically a fast charging station with typical electric grid connection and commercially available fast charging station developed and produced by Ekoenergetyka in cooperation with the author.…”

The most suitable way, to eliminate simultaneously all side effects connected with the application of power electronic converters in Smart Grid systems, is the compensation of the interference sources inside of the power electronic interface. In such situation the compensation of the interference sources prevents both the spreading of the interference over extensive circuits and the uncontrolled aggregation of the interference generated by a group of converters, facilitating development of the compatible system. CM Compensator for InvertersThe CM voltage source cancellation in inverter-fed systems [25] can be done using active [54] as well as the passive CM voltage compensators proposed by 37,38]. Compensation in the active series filter is realized by the addition of the common mode voltage of the opposite polarity to each phase. It has been realized using the emitter follower (T 1 , T 2 ). The common mode voltage is detected on Y -connected capacitors (C det ) and added to the phase voltages by a common mode transformer, Fig. 5.1.The equivalent circuit for CM component is presented in Fig. 5.2. The series compensation is realized by addition of the compensating voltage U C by means of the CM adding transformer fed by the voltage-controlled voltage source.The original arrangement proposed by Ogasawara and Akagi for CM voltage, bearing voltage and bearing current elimination was designed using bipolar transistors for a 3 × 200 V, 60 Hz supply of a frequency converter. Each transistor of the emitter follower has to operate under full DC-link voltage conditions (282 V) [38].In the presented investigations the concept of the series active filter for a 3×400 V,

“…Considering the characteristics of different energy storage media, the energy type represented by the battery or the power type storage medium represented by the super capacitor is combined with the cascade type converter to form the high voltage and large capacity energy storage device.However, cascading PCS will encounter many problems in the application. In [2] , the problems of cascade energy storage system in practical application are summarized in detail. In order to ensure that the cascade PCS is working properly, it must maintain a dynamic balance with the power delivered by the AC grid, so it is necessary to effectively control the output power.…”

Keywords: renewable energy sources, high voltage and large capacity, power conversion system, cascaded H-bridge, energy storage medium.Abstract. The fluctuation and intermittence of renewable energy sources power poses a great challenge to the stable operation of power system, which needs power conversion system(PCS) to provide spare power to achieve dynamic balance of supply and demand for the power grid. Cascaded H-bridge converter is a main topology structure for the application for high voltage large capacity grid, which is combined with different energy storage media, having broad application space in the large capacity storage places. This paper introduces the topology of cascaded H-bridge PCS, expounds the various control strategies under different energy storage media and mainly analyzes and evaluates the various control methods, whose respective advantages and disadvantages are also summarized, providing reference for the theory research and practical application.
