All proposed topologies demand significant amount of semiconductor components and input dc supplies, which is considered the main drawback for the implementation of three phase cascaded MLIs. This paper proposes a new generalized concept that could be employed within any existing cascaded MLI topology in order to reduce its size in terms of device count including semiconductor switches, diodes, and dc power supplies. The new generalized concept involves two stages namely, cascaded stage (CS) and phase generator stage (PGS). The PGS stage is a combination of conventional three phase two level inverter (CTPTLI) and three bidirectional (BD) switches, while the cascaded stage can be modified using any existing cascaded topology. The proposed concept is validated through extensive simulation and experimental analyses. Results show the capability of the proposed technique in reducing device count of the existing topologies while maintaining its performance.","PeriodicalId":104496,"journal":{"name":"2017 Ninth Annual IEEE Green Technologies Conference (GreenTech)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131203352","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 SMES is integrated to the grid using a pulse-width-modulated current source converter (PWM-CSC) which is an straightforward alternative to conventional topologies due to its intrinsic current characteristic. Dynamics of this converter is modeled by using an averaged model which considers the modulation indexes as control inputs. A hyperboloid Hamiltonian function is selected to design the closed-loop control law in the 0dq reference frame. A sensitivity analysis is performed on the proposed control. Results demonstrate the stability and efficiency of the proposed control on a medium-voltage grid under different operative conditions.","PeriodicalId":104496,"journal":{"name":"2017 Ninth Annual IEEE Green Technologies Conference (GreenTech)","volume":"533 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123576109","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}

Accurate detection of distributed energy resources (DERs) islanding from utility grid is necessary to initiate any control action within the microgrid. In order to detect islanding occurrence, an adaptive synchronous reference frame phase locked loop (ASRF-PLL) has been utilized in this paper. This modified PLL provides stable operation in grid connected and islanded mode and maintains frequency to its nominal value. Furthermore, droop control for frequency and voltage amplitude restoration under different islanding scenarios has been discussed. Islanding operations studied in this paper are independent synchronous generator (SG), parallel inverters feeding the local loads, and hybrid islanding including both SG and inverter based DERs. Simulation results are presented for aforementioned islanding scenarios which validate the effectiveness of proposed islanding detection algorithm and control techniques to keep voltage amplitude and frequency within prescribed limits.","PeriodicalId":104496,"journal":{"name":"2017 Ninth Annual IEEE Green Technologies Conference (GreenTech)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125182707","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}

During asymmetrical faults the major challenge is to limit the inverter current and keep it within limits so that the inverter relay does not trip. Such a control methodology ensures seamless power to the consumers without damaging the inverter. In this paper a second order generalized integrator based inverter control operating like a virtual synchronous machine is proposed. The calculations for the inverter control states are performed on a per phase basis and the control algorithm is developed. The dynamic equations describing the proposed control algorithm with its analyses is presented in this paper. Numerical simulations based on MATLAB/Simulink are performed to verify the efficacy of the proposed control technique on a three phase grid connected inverter.","PeriodicalId":104496,"journal":{"name":"2017 Ninth Annual IEEE Green Technologies Conference (GreenTech)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126638325","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 significant increase of electricity demand in Saudi Arabia means that power generation will expand and that will lead to increased consumption of fossil fuels. This rapid increase of the conventional generation is the major cause of environmental pollution and impacts on human health. Studies show that power demand in the Kingdom of Saudi Arabia (K. S. A) is expected to continue its significant increase to reach more than 100000 MW over the coming 10-15 years. Also, that will affect the fuels exportation and the country's revenue earning. Meanwhile, the main goal of the KSA 2030 vision is focusing on the economy and prosperity. Because of that, it is essential that an alternative method of electricity production is found to reduce the country's power generation dependence on fossil fuel.","PeriodicalId":104496,"journal":{"name":"2017 Ninth Annual IEEE Green Technologies Conference (GreenTech)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123063339","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}

Internet of things (IoT) based online load forecasting (LF) collects those data from internet on demand and then performs fast statistical and optimization methods for forecasting efficiently. IoT based online LF not only depends on power systems properties, but also internet, machine-to-machine (M2M) connections, communications and computation facilities. Limitations for better utilization, reliability, stability and control of smart grid technologies make it different from traditional load forecasting. Power systems are typically large, complex and distributed. In this study, load data is collected from smart meters and stored as historical load data. However, weather data at a given geographical location including temperature, humidity, wind speed, wind direction, heat, sunlight, solar radiation, rainfall and so on with good accuracy are collected from internet on demand. Computations are done in two steps: first neural network (NN) training to map the dynamics of load and then an optimization on the NN weights to improve overall forecasting error. NN is an effective mathematical tool for mapping complex relationships. On the other hand, particle swarm optimization (PSO) is used because it is the most promising swarm based optimization tool. Results show the effectiveness of the proposed online short term load forecasting in IoT.","PeriodicalId":104496,"journal":{"name":"2017 Ninth Annual IEEE Green Technologies Conference (GreenTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131842880","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 electrolytic cell is comprised of a crucible with hollow cylindrical partitions filled with molten lithium carbonate. Voltage is applied through the electrodes that are comprised of a cylindrical cathode surrounded by two cylindrical anodes. Hot CO2 is bubbled into the electrolyte and serves as an extra heat source in addition to replenishing the carbon deposited during electrolysis. If the electrolysis is carried out at thermoneutral potential, and thus the exothermic dissolution of CO2 is the only reaction that generates additional heat in the system. On the other hand, applyingoverpotentialwill generate additional heat and thus help mitigate radiation losses. We study the interplay of these various parameters by using COMSOL Multi-physics software to simulate the experimental setup. The captured CO2 rate of the electrolyte and the input temperature, as well as applying overpotential, will influence the results. Detailed results presented here can thus guide the experiment in choosing the suitable settings.","PeriodicalId":104496,"journal":{"name":"2017 Ninth Annual IEEE Green Technologies Conference (GreenTech)","volume":"287 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132348554","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}
