Solar photovoltaic (PV) systems are currently being deployed at an accelerated rate because of their cost-competitiveness and environmental benefits, which make them a prime candidate for local renewable energy generation in communities. Microgrids can help accommodate for the problems that accompany PV systems, such as intermittency due to weather, by coordinating different distributed energy resources (DERs), while islanded or by drawing power from the utility while in grid-connected mode. An islanding option is also important for resilience and grid fault mitigation, even if other DERs are not present within the system. This paper studies the potential benefits that a multi-MW …
Optimization Of Union College’S Microgrid To Meet All Load With A Least-Cost, Low-Carbon Energy Mix, Caitlin Mcmahon
Optimization Of Union College’S Microgrid To Meet All Load With A Least-Cost, Low-Carbon Energy Mix, Caitlin Mcmahon
Honors Theses
A microgrid is a localized electric grid that generates some or all of the power used to meet its load. Union College currently has a microgrid that meets 70 percent of the campus’ load and is connected to the main grid. It is made up of a cogeneration plant as well as solar photovoltaic panels and wind turbines, which are renewable energy sources. The goal of this project is to determine the least cost, low-carbon energy mix that meets 100 percent of the campus’ load. The issue with solar and wind power is that they are variable based on time …
Artificial Intelligent Based Energy And Demand Side Management For Microgrids And Smart Homes Considering Customer Privacy, Ahmed F. Ebrahim
Artificial Intelligent Based Energy And Demand Side Management For Microgrids And Smart Homes Considering Customer Privacy, Ahmed F. Ebrahim
FIU Electronic Theses and Dissertations
The rapid development of various power electronics applications facilitates the integration of many smart grid applications in recent years. However, integration of intermittent renewable energy sources, highly stochastic electric vehicles (EVs) activities on the grid and time-varying smart loads have increased the level of grid vulnerability to unusual and high complexity and quality-related problems. Among these problems is to accurately estimate the real contribution and consumption of household loads, in the era of smart appliances and interoperability operation, and its relative impact to the grid’s operation. Specifically, household loads represent a significant percentage of electrical energy consumption and, therefore, could …

Modern smart homes are being equipped with certain renewable energy resources that can produce their own electric energy. From time to time, these smart homes or microgrids are also capable of supplying energy to other houses, buildings, or energy grid in the time of available self-produced renewable energy. Therefore, researches have been carried out to develop optimal trading strategies, and many recent technologies are also being used in combination with microgrids. One such technology is blockchain, which works over decentralized distributed ledger. In this paper, we develop a blockchain based approach for microgrid energy auction. To make this auction more …
Computational Intelligence Approaches For Energy Optimization In Microgrids, Tamal Roy
Computational Intelligence Approaches For Energy Optimization In Microgrids, Tamal Roy
Electronic Theses and Dissertations
The future electrical system termed as smart grid represents a significant paradigm shift for power industry. Nowadays, microgrids are becoming smarter with the integration of renewable energy resources (RESs) , diesel generators , energy storage systems (ESS), and plug-in electric vehicles (PEV or EV) . However, these integration bring with new challenges for intelligent management systems. The classical power generation approaches can no longer be applied to a microgrid with unpredictable renewable energy resources. To relive these problem, a proper power system optimization and a suitable coordination strategy are needed to balance the supply and demand. This thesis presents three …
Microgrid-Enabled Reactive Power Support To Enhance Grid Economics, Sarhan Hasan
Microgrid-Enabled Reactive Power Support To Enhance Grid Economics, Sarhan Hasan
Electronic Theses and Dissertations
Reactive power plays an essential role in voltage control and stability in electric power systems. Various Volt/VAR techniques are utilized in electric power systems to maintain the voltage profile within defined acceptable limits and accordingly provide reliability and stability. Reactive power has been commonly generated through large-scale synchronous generators or distributed capacitor banks to provide proper transmission and distribution level system management, however, reactive power can be further used as an effective means to reduce total system operation cost. In this dissertation, an optimal reactive power model is proposed to determine the optimal nodal reactive powers that result in the …

A Four-Port Bidirectional Dc-Dc Converter For Renewable Energy System And Microgrid, Xia Du
All Graduate Theses, Dissertations, and Other Capstone Projects
Renewable energy has nowadays become important in electrical power applications. Power converters play an important role in integrating these distributed energy sources. However, due to their intermittence characteristics, e.g., the output power provided by the PV and wind turbine is not stable, either an energy storage system will be used or microgrid is formed between the main grid and the sources. To integrate these renewable energy sources and manage the power flow, a multiport converter is preferred because it is highly beneficial and cost-efficiently than the traditional solution that using multiple individual power converter for each source. This thesis proposed …
