This application is suitable for uninterruptible power supply (UPS) systems. Finite control set model predictive control (FCS-MPC) has proved to be a good candidate for controlling such kind of devices. FCS-MPC relies on accurate system model to achieve high performance. However, output load is not always known for UPS applications. Under this condition, the use of observers to estimate the output load currents is a good solution. In this paper, a FCS-MPC strategy using an unknown input observer (UIO) is assessed. To design the UIO, the nature of the output load has been considered. This paper is focused on output loads with sinusoidal output currents. Two different UIO are evaluated. The first one uses a conventional approach and the second one takes into account the sinusoidal nature of the output load currents. Experimental results in a VSI prototype show that the second approach can provide superior performance independently of the output load connected to the power inverter.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"23 Suppl 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131166587","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}

Finally, an analytical method is proposed to enhance pf without compromising machine torque density. There are many models examined in this study to verify the design process.

First step is to investigate the effects of stator slot number for the same number of the pole. Different winding schemes such as distributed, concentric, single layer, double layer configurations are studied to reach a better stator design. As a final step, optimizations on stator slot shapes, slot openings, teeth bottom geometries and air gap length are carried out and all the results are presented.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131616117","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}

This leads to a decreased number of conventional power plants. However, conventional power plants still play a major role when it comes to voltage and frequency control. Thus, the remaining power plants in the system together with the renewable power supply units have to carry out those control actions in the future. To cope with these ongoing changes in the power system, conventional power plant operators are working on increasing the flexibility of their power plants. One aspect of power plant modernization is exchanging the automatic voltage regulator (AVR) of the synchronous generator. Oftentimes an old lead-lag controller is replaced by modern proportional-integral-derivative (PID) control. This paper shows how to use particle swarm optimization to tune the parameters of such PID regulators to significantly improve transient voltage behavior. AVR optimization is not new to the scientific community. However, most approaches are using simple linear control circuits representing excitation system and synchronous generator as PT1-elements. This paper uses dynamic non-linear models to represent the excitation system and the power system components and, thus, gives a very practical insight. Optimization results are evaluated within a simple single generator system and a nine bus benchmark system.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"396 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133233383","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}

Specifically, this paper will focus on the introduction of meteorological variables other than temperature to reduce forecasting error. The forecasted variables of solar radiation, cloudiness and wind velocity are included in the proposed forecasting model and their effect is analyzed in terms of overall accuracy.

The impact of renewable energy sources in the electrical grid mainly depends on their nature, their penetration rate and the topology of the grid. This paper addresses how a representative power quality parameter (the number of voltage dips) are affected by the inclusion of renewable energy sources. Specifically, the Italian grid is analysed. This grid is of particular interest as the features of the renewable energies installed and the grid connectivity differ depending on the geographical regions. The paper studies if there is a potential linear correlation through two indices (Pearson's index and the p-value). It is generally observed that the more power the RESs deliver, the less number of voltage dips occur. However, we demonstrate that this condition does not always hold.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"352 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122846752","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}

It is shown that by using reactive power reserves of available resources and/or reactive power flows in important lines the current margin can be estimated with given accuracy.

In this paper, a modulation method as a modified version of conventional phase-shifted PWM is presented when the CHB converter has a large number of power cells.

These are harmonics which fall in the frequency range 2 to 150 kHz. Power electronics has consolidated as a ubiquitous technology, which also plays a critical role in this subject. Broadly speaking, these HF components are due to the normal operation of electronic converters and the switching techniques employed. The paper presents measurements of waveform distortion from several illustrative facilities and loads. Recent studies indicate that future problems to distribution grids may include supraharmonics. Grid-tie inverters are an origin of waveform distortion, still in this frequency range, but, can also be the pillar to mitigate it, when methodologies like random pulse with modulation or modular multilevel converter are properly applied.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115131913","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}
