[IEEE 2018 International Conference on Control, Power, Communication and Computing Technologies (ICCPCCT) - Kannur,Kerala, India (2018.3.23-2018.3.24)] 2018 International Conference on Control, Power, Communication and Computing Technologies (ICCPCCT) - A Comparative Analysis of PID and Fuzzy Logic Controller in an Autonomous PV-FC Microgrid
摘要： In this work, the dependability and performance analysis of a typical hybrid micro-grid compiled with Photovoltaic (PV) arrays and Solid Oxide Fuel Cell (SOFC) is bestowed. The micro-grid is designed to operate in an islanding/autonomous mode to attain the load demand. The Fuzzy Logic Controller (FLC) based Voltage-frequency control (V/f) is applied to effectually control the micro-grid voltage and frequency; the easy flow of power can be achieved from generation to consumption. The voltage as well as the frequency of the proposed micro-grid is consistent even if there is a sudden load or power fluctuation. A dc-dc converter is used to connect the PV and the SOFC to the dc grid. Voltage Source Converter (VSC) helps to maintain the output voltage by enforcing the implementation of Maximum Power Point Tracking (MPPT) techniques by P & O algorithm. When the State of Charge (SOC) falls to its minimal limit, the rated power can be attained by a backup generator called SOFC. The propounded PV-SOFC hybrid micro-grid is critically investigated to scrutinize its performance improvisation by extensive simulation analysis. The system’s improvement in power quality can be demonstrated with the help of results presented. A relative analysis is carried out to study the proposed system with conventional PID Controller is also presented.

[IEEE 2018 International Conference and Exposition on Electrical And Power Engineering (EPE) - Iasi, Romania (2018.10.18-2018.10.19)] 2018 International Conference and Exposition on Electrical And Power Engineering (EPE) - Establishing an Optimal Residential RES PV Source by Modelling
摘要： The analyzed Microgrid (MG) is implemented in the Research Centre of Transilvania University of Brasov Institute and consists in an 8 kW photovoltaic (PV) system, a grid connecting PV inverter of 4.6 kW and a 48V Li-ion stationary battery interfaced with the MG by a 6 kW inverter which provides around 20 kWh storage capacity. The main issue of this paper is to establishing by modeling, an optimal residential PV renewable energy source (RES), that provide for a given inverter the best energy production based on the solar potential from Brasov area. Simulations are accomplished in Homer Pro software in order to estimate the optimal PV power source to obtain a maximum amount of energy for a given PV system structure.

[IEEE 2018 7th International Conference on Renewable Energy Research and Applications (ICRERA) - Paris, France (2018.10.14-2018.10.17)] 2018 7th International Conference on Renewable Energy Research and Applications (ICRERA) - From Solar Microgrid Simulation to Field Deployment: Accuracy and Uncertainties
摘要： Economical, stand-alone, solar microgrids can be quickly implemented in most un-electrified regions of the world. Solar resource maps developed by the National Aeronautics and Space Administration (NASA) and the National Renewable Energy Laboratory (NREL), together with HOMER Pro software, have been widely used to determine the optimal design of microgrids. Repercussions of imprecise predictions of solar resources and electrical power generation lead to an increased likelihood of energy shortage in a stand-alone microgrid, or increases overall project costs. Actual solar energy productions of two sites in Kerala, India, were compared with solar electricity generation, predicted by the HOMER Pro tool. For both test sites, the results showed that the simulated, solar production was within 8.1% of the actual annual production. However, monthly variations in solar production led to unanticipated energy shortages in the simulated microgrids. These findings reaffirm the inexorable need of the following actions for cost-effective design of microgrids: a) systematic analysis of reliability of electrical supply, and b) deployment of schemes for demand response and flexible load. Statistical analysis of temporal variation of solar irradiance in the United States were used to inform recommendations for stand-alone microgrid design.

[IEEE 2018 International Conference on Control, Power, Communication and Computing Technologies (ICCPCCT) - Kannur,Kerala, India (2018.3.23-2018.3.24)] 2018 International Conference on Control, Power, Communication and Computing Technologies (ICCPCCT) - SEPIC-CUK Converter For PV Application Using Maximum Power Point Tracking Method
摘要： Solar energy is the most important and freely available energy source which generates in DC form, which requires power electronic devices to adapt its output to requirements. The conventional SEPIC and CUK converters are formed by two inductors, link capacitors, switch and diode. The CUK is a negative output converter, while the SEPIC is a positive output the SEPIC-CUK configuration it is observed that both converters have the same voltage conversion ratio with opposite polarity. Bipolar DC link has two wires one with positive polarity and one with negative polarity. In normal operation, the current through ground is zero. It has two voltage levels, allowing fault conditions a monopolar operation. The main advantage of the proposed configuration is that it allows implementation of bipolar DC link with only one controllable switch. The system can be connected to the AC or DC micro grids. Linear Variable structure control MPPT algorithm is use to extract maximum power from the PV module and also to control the switch.
