The neutral of the grid can be directly connected to the negative terminal of the source (PV). It consists of four power switches, one diode, one capacitor and a small filter at the output stage. A simple Unipolar Sinusoidal Pulse-Width Modulation (SPWM) technique is used to modulate the inverter to minimize switching loss, output current ripple and filter requirements. The main advantages of the new inverter topology are: (1) the negative polarity of the PV is directly connected to the grid, so no leakage current, (2) voltage stress of all switches are the same and equal to the dc-link voltage, (3) reactive power can be send to the grid, so no problem of reactive power compensation (4) peak of output ac voltage is equal to input dc-voltage (unlike NPC, ANPC and some topologies, which requires two times of the peak ac-voltage magnitude) and, (5) the flying capacitor charges every switching cycle, which reduces the size of the required capacitor with switching frequency. In addition, industry standard half bridge module can be used in the new inverter without any modification. Experimental results of 1 kW prototype are presented at the end of the paper to prove the concept and theoretical analysis of the proposed transformerless inverter. The peak efficiency of the inverter at a full load is 99.2%.","PeriodicalId":156411,"journal":{"name":"2016 IEEE 7th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124436106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed scheme provides power factor correction (PFC) with respect to the back-EMF of a permanent magnet synchronous generator (PMSG) instead of the terminal voltage. Since there exists a series impedance between the back-EMF and terminal voltage, performing PFC with respect to the terminal voltage leads to the additional reactive power generated by the back EMF. This additional reactive power degrades the capacity of the generator. In this paper, a novel three-phase reactive power control technique based on the one-cycle control scheme is presented in order to eliminate the need for additional reactive power. In the proposed technique, the terminal voltage and current of each phase are measured and the optimal power factor is regulated at the generator's terminals. The optimal reactive power is determined in the proposed control scheme by introducing a fictitious reactive current, derived from the input voltage, in the control law. The simulation and experimental results show the optimal performance of the proposed technique in terms of reactive power.","PeriodicalId":156411,"journal":{"name":"2016 IEEE 7th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122686444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating DSM and DERs into a cohesive, networked package that fully utilizes smart energy-efficient end-use devices, advanced building control/automation systems, and integrated communications architectures, it is possible to efficiently manage energy and comfort at the end-use location. In this paper, an ontology-driven multi-agent control system with intelligent optimizers is proposed for optimal real-time dispatch of an integrated building and microgrid system considering coordinated demand response (DR) and DERs management. The optimal dispatch problem is formulated as a mixed integer nonlinear programing problem (MINLP) and solved through an agent-based approach.

In 2013, US DCs consumed an estimated 91 billion kWhr of electricity - enough electricity to power all the households in NY City twice over - and are on-track to reach 140 billion kWhr by 2020 [1]. Paper presents development of `Multi-Level Static Synchronous Compensator Inverter' (MLSTATCOMI) for DC application using Space vector PWM (SVPWM) based digital controller at Medium Voltage (MV) application. MV operation reduces overall electrical losses and reduces Power Usage Effectiveness (PUE) of DC. Reactive power STATCOM compensator along with battery energy storage provides active power compensation also. Capacitor voltage balancing of ML inverter is not an issue with reactive power STATCOM compensator as active power transfer is almost zero. Capacitor voltage balance depends on net transfer of active power between Inverter DC-link voltage source and AC grid source [2]. Capacitor voltage balancing is an issue of MLSTATCOMI compensator as it needs to compensate both active and reactive power. DSP and FPGA based SVPWM digital controller is developed to compensate simultaneous active and reactive power compensation. ML capacitor voltage balancing is achieved by developing a unique switching sequence of Inverter space vectors. The modulator performance using SVPWM control strategy can be extended to five-level inverter using space vector [3] for DC application.","PeriodicalId":156411,"journal":{"name":"2016 IEEE 7th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134485081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such strategies require accurate information regarding the rotor position and speed in order to set the dq frame reference currents and to perform the necessary frame transformations. This information can be obtained using a rotor speed sensor (i.e. a shaft encoder) or via a sensor-less strategy in which a dynamic machine model and stator current measurements are used to estimate the true rotor position. This paper now presents an alternative approach to control the active/reactive power supplied by the WECS permanent magnet synchronous generator (PMSG). The proposed strategy uses the three phase converter modulation commands to identify the phase and frequency of the PMSG stator terminal voltages. This enables the direct regulation of the real and reactive power extracted at the PMSG terminal voltages using a stationary frame Proportional + Resonant (PR) stator current regulation strategy, without requiring precise knowledge of the rotor position. Maximum power point tracking (MPPT) functions are realized using the measured PMSG terminal voltage frequency to form an estimate of the rotor speed. The result is a simple robust WECS control strategy that rapidly and accurately tracks rotor speed changes caused by wind speed variations. Detailed simulation and experimental results obtained for a scaled laboratory prototype system are presented to validate the proposed strategy.","PeriodicalId":156411,"journal":{"name":"2016 IEEE 7th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115616479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
