The steps for robust SOC estimation in the proposed approach as follows. First, after discharging/charging of the battery pack, an obtained EDCV signal is decomposed into different frequency sub-bands (low-and high-frequency components, An and Dn) using the DWT-based multi-resolution analysis (MRA) method. Second, a low frequency component An is specifically served as a terminal voltage and sent to the equivalent circuit model (ECM)-based SMO for obtaining SOC information. The ECM of the battery pack previously constructed by discrimination process that selects unit cells with similar electrochemical characteristics is well considered. Finally, the SOC performance is compared with that of Ampere-hour counting for validation of this proposed work. Experimental results clearly show that this approach sufficiently enables us to provide a reliable SOC estimation whole discharging/charging period using only fundamental ECM without additional consideration such as internal state variation and noise model for compensating the ECM errors. This approach used two experimental packs of 6S1P and 8S2P that respectively connected in series and in series/parallel using 2.2Ah unit cells discriminated in advance.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"71 1","pages":"22-27"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76061688","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}

An Inverter Molecule is a building block for a novel distributed inverter architecture suitable for PV/Battery applications which exceeds the performance metrics obtained by Central/String- inverters with or without DC/DC optimizers or by Micro-Inverters. The proposed transformerless architecture utilizes low-voltage semiconductor devices with much higher yields than their high-voltage counterparts. A group of Inverter Molecules operate autonomously and cooperatively to maintain the grid interconnection requirements while providing maximum power control on each molecule's PV panel. This paper overviews the state-of the-art control methods implemented mostly on cascaded H-bridge derived topologies and further establishes a distributed control scheme for Inverter Molecule architecture that does not need any high bandwidth communications except a heartbeat signal at line frequency. Experimental results are presented for a lab-scaled prototype.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"5 1","pages":"1130-1135"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75655844","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}

However, the resultant estimated rotor position has an angle ambiguity of π due to the lack of magnetic polarity information in these saliencies. Therefore, this paper utilises the high frequency (HF) inductance (permeance) harmonics (i.e., HF saliency) generated due to the saturation modulation between HF field and main flux field for rotor position estimation. Since the HF saliency contains the magnetic polarity information, the resultant carrier responses due to the interaction between HF field and HF saliency (i.e., the secondary harmonics) can be utilised for the actual rotor position tracking without any ambiguity of machine polarity. This will not only eliminate the time-consuming process of polarity identification but also enhance the position estimation robustness and stability. Finally, in order to validate the effectiveness of HF saliency based sensorless control strategies, experiments are carried out on a laboratory permanent magnet synchronous machine.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"4 1","pages":"837-844"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74529008","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}

Regulations have been imposed on the PV systems, where more active power control should be flexibly performed. As an advanced control strategy, the Absolute Active Power Control (AAPC) can effectively solve the overloading issues by limiting the maximum possible PV power to a certain level (i.e., the power limitation), and also benefit the inverter reliability. However, its feasibility is challenged by the energy loss. An increase of the inverter lifetime and a reduction of the energy yield can alter the cost of energy, demanding an optimization of the power limitation. Therefore, aiming at minimizing the Levelized Cost of Energy (LCOE), the power limit is optimized for the AAPC strategy in this paper. The optimization method is demonstrated on a 3-kW single-phase PV system considering a real-field mission profile (i.e., solar irradiance and ambient temperature). The optimization results have revealed that superior performance in terms of LCOE and energy production can be obtained by enabling the AAPC strategy, compared to the conventional PV inverter operating only in the maximum power point tracking mode. In the presented case study, the minimum of LCOE is achieved for the system when the power limit is optimized to a certain level of the designed maximum feed-in power (i.e., 3 kW). In addition, the proposed LCOE-based analysis method can be used in the design of PV inverters considering mission profiles.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"62 1","pages":"28-34"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72816930","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}
