Modeling Electric Energy Generation In Ercot During Extreme Weather Events And The Impact Renewable Energy Has On Grid Reliability, Adam R. Ruthford, Bivin Sadler
Modeling Electric Energy Generation In Ercot During Extreme Weather Events And The Impact Renewable Energy Has On Grid Reliability, Adam R. Ruthford, Bivin Sadler
SMU Data Science Review
This paper shows the inadequacy of current grid backup supplies, their ongoing threat to grid reliability, and the increased risk of customer blackouts. This paper also examines reliability concerns caused by renewable energy sources under more normal operating conditions. This paper seeks to model the impacts of extreme weather on ERCOTs grid. Unusual weather patterns require that the electrical grid operates in conditions outside normal operating parameters. Electrical system demand can spike well above normal levels. At the same time, weather influences can change the operating envelope of electrical generation equipment. The ERCOT grid has changed from its’ traditional mix …
Why Indonesia Needs A New Energy Paradigm, Aditya Prasetyo
Why Indonesia Needs A New Energy Paradigm, Aditya Prasetyo
English Language Institute
The problem of Indonesia's dependence on petroleum as its main energy source can be overcome by instead using an energy mix. This study focuses on optimal utilization of other energy resources that can help to meet the demand for energy in Indonesia and help to reduce its dependence on oil, thereby preventing a future energy crises.

2021 Department Of Energy Collegiate Wind Competition Electrical System, Grayson Capers, Shane Alayvilla, Justin Rodrigues
Electrical Engineering
In this work, the implementation of the electrical system for Cal Poly’s 2021 Department of Energy Collegiate Wind Competition turbine is described. The mission of this project was to complete the turbine testing tasks to the best of the team’s ability. This system includes an off the shelf slotless permanent magnet synchronous generator and rectifier to produce a DC voltage. To maximize the power output at below-rated wind speeds, current sensors, voltage sensors, and a dynamic load with variable resistance were designed and tested. To curtail the power and rotor speed in high wind events, the turbine was equipped with …
Exploring Renewable Energy Futures In Humboldt County Consistent With The Goals Of California’S Renewable Portfolio Standard, Amin M. Younes
Exploring Renewable Energy Futures In Humboldt County Consistent With The Goals Of California’S Renewable Portfolio Standard, Amin M. Younes
Cal Poly Humboldt theses and projects
Humboldt County has abundant wind, solar, and biomass resources, but has made limited progress towards the state’s 2045 requirement of 100% clean electricity. A recently rejected onshore wind project showed that technically and economically viable projects can fall to social and political challenges, emphasizing the need for social considerations in renewable transitions. I therefore integrated community members’ preferences into modeling of RPS-consistent renewable energy scenarios in Humboldt County. My model suggests that offshore wind, utility-scale solar, distributed solar, and biomass power are technically and economically viable sources of significant local generation at varying costs.
In interviews with energy-engaged residents, I …

The amount of cloud cover present in the sky is a significant factor when determining the solar radiation impinging on a solar panel. The optimum tilt required to achieve maximum energy impingement on a surface is also influenced by the amount of cloud cover. This work presents a method for determining the optimum tilt angle for a fixed solar panel when a set amount of cloud cover is present in the sky. Fixed tilt angles that have the most incident solar energy over the course of a year as a function of cloud cover, latitude, and azimuthal angle orientation are …
