The displacement of the traditional generating plants requires the new resources to be involved in the grid control strategy. This has driven the research to the so called grid-supporting control strategies which allow power converters to be involved in the grid voltage and frequency regulation. This paper presents a performance based comparison of three families of converter control strategies: grid-forming, grid-following converters and virtual synchronous machines. The CIGRE medium voltage benchmark system is used as a test bench and the performance of the three strategies are compared each other and with those of a traditional reciprocating generator. The analysis is made thought real-time simulations.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114879850","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}

Vast amount of research is being carried out to unravel this condition and elucidate a potential solution while the current power system is sustaining with the upgrades of certain technological improvements. This paper proposes a method which utilizes a Battery Energy Storage System to be incorporated with a grid connected solar photovoltaic system to facilitate the voltage regulation in the utility side. The battery energy storage system is expected to store energy during high solar photovoltaic generation or low power demanding conditions while supplying energy back to the system during low solar photovoltaic generation or high-power demanding conditions. The modeling and simulation of the proposed system is implemented, and the system performance is investigated for several circumstances with varied solar photovoltaic generation for different battery states.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121519480","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 major merit of this novel machine concept is the use of complementary rotors, which consist of an inner rotor and an outer rotor that are mechanically staggered by 180 electrical degrees, to provide complementary paths for the PM excitation flux. Two layers of PMs are employed, located on the inside and outside of the slots. Meanwhile, with only salient poles, the rotors are mechanically robust. The investigation is based on 12 stator pole machines with 10, 11, 13 and 14 rotor poles. Electromagnetic performance measures including flux linkage, back electromotive force (EMF), torque characteristics, loss and efficiency are comprehensively studied using the finite element method (FEM). The results show that the machine with 11 rotor poles can achieve the largest torque density and rated efficiency, as well as minimum ratio of cogging torque to rated torque.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129575285","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 method is explained with the model of grid connected voltage source inverter with and without converter losses. The implementation of the control method does not require phase-locked-loop resulting in improved efficiency and response time. Further, an algorithm is proposed to generate the reference power required to implement the direct power control with maximum power point tracking for multisource photovoltaic system. The proposed control method and algorithm is implemented with switched capacitor based boost multilevel inverter. The simulation results under varying irradiance and reactive power are presented.

In the developed world, as the conventional distribution grids are based on AC, a hybrid approach of AC and DC grids and assets seems to be a good approach. Therefore, an increasing attention on the utilization of hybrid DC -AC nanogrids is expected to hostsmart building enabling technologies and to accommodate high RES penetration and gain technoeconomical advantages This paper explores and analyzes these advantages focusing on the case study of the hybrid nanogrid of the University of Cyprus and examines the economic gains of the system based on a techno-economic analysis of the FOSS Research Centre for Sustainable Energy nanogrid.

Despite that look-up table is common way to obtain firing angle from input susceptance by searching for the appropriate angle from a table with pre-calculated values, the regression model based approach shows better perfomance in terms of increasing speed of calculations and simplicity of modelling.
