This grid connected micro-grid also contains two solar Photo Voltaic (PV) systems, two Wind Turbines each contains a local consumer, a solar PV system and a battery unit. We also consider a Diesel Power Plant that provides considerable power. So, Initially we measure the load patterns, solar power, wind power generated in the two solar and wind units. Then we use Multi Agent System for advanced distributed energy management of this solar-wind micro-grid with smart grid frame work. We develop a simulation model in Java Agent Development Environment (JADE) for distributed, dynamic energy management, which considers the intermittent nature of solar power, wind power, randomness of load, dynamic pricing of grid and variation of critical loads and choose the best possible action every hour to stabilize and optimize the solar micro-grid. Furthermore, MAS increases the operational efficiency, due to decentralised approach and reduced timings. Thus MAS in solar micro-grid energy management leads to economic and environmental optimization. Simulated operation of solar generators and loads are studied by performing simulations under all possible agent objectives. Outcome of the simulation studies proves the effectiveness of proposed MAS in distributed energy management of solar-wind interconnected micro-grid.","PeriodicalId":308604,"journal":{"name":"2016 3rd International Conference on Electrical Energy Systems (ICEES)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115792921","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}

Several multi-carrier modulation methods with miscellaneous properties have been already known. While evaluating and comparing these methods, such as PD, POD and APOD through measures like total harmonic distortion (THD) the paper shows their advantages for applications of Cascade multi-level topologies by simulation results.

The Induction Generator is a Doubly Fed Induction Generator (DFIG) used in a Wind Power Conversion System (WPCS). The DFIGs interconnected with the grid are very much sensitive to any disturbance in the grid. The stator of the generator is directly connected to the grid. Hence occurrence of any fault near the grid, immediately leads to a sag in the stator voltage of the generator causing overcurrents as well as overvoltages in the rotor windings. As a result there is a chance of damage of the partial fraction Rotor Side Converter (RSC) during fault. In order to protect the converter, here in this paper a new crowbar protection design is adopted along with the proposed control technique. The proposed strategy is validated through simulation results. The Simulations are carried out in MATLAB on a 1.7 MVA DFIG system and the effectiveness of the new protection design is verified.","PeriodicalId":308604,"journal":{"name":"2016 3rd International Conference on Electrical Energy Systems (ICEES)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114870007","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}
