“…This type of converter is recommended for voltage matching between DC type renewable energy sources, fuel cells or DES that produce low DC voltage and the common DC bus of the system [1,8,12,13,16,39,41,50,57], such as the one presented in Fig. 1.8.…”

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,

“…Until now there is any storage system which is capable to save large amount of energies for a reasonable amount of time with a small size and price. Third, the integration requires advanced power converters [9][10] as well of specific control algorithms for frequency synchronization, voltage/var control, protection, fault detection, isolation and reconfiguration [11][12][13][14][15][16]. The technology is still in development and more research is necessary to have a good performance.…”

Although numerous proposals for electrical and communication topologies for distribution automation had been presented, not all of them are suitable for the use of renewable energy as a source of electricity. Selecting the most appropriate topology requires good knowledge of the particular characteristics and requirements. This paper presents the analysis of the basic characteristics, topologies and the main functions of the distribution network and evaluates the communication architecture suitable for a sustainable energy resources integration. Finally, recommendations for a new architecture are presented as well as for the communication to use.

“…In order to achieve the assumed high level of renewable energy content the application of advanced metering and control techniques (grid automatic enabling island operation contributes to increased reliability), energy storage devices, and demand management techniques e.g. active demand response (ADR) are required [6,16,18,19,25,31,43,54,55,67,68,72,73,75,82,112]. • A typical feature of this system is the high quality of electric energy, elimination of higher range harmonics, voltage dips, sags, interruptions, and asymmetry of phase voltages.…”
