Modeling, Simulation And Control Of Hybrid Electric Vehicle Drive While Minimizing Energy Input Requirements Using Optimized Gear Ratios, Sanjai Massey

Dissertations, Master's Theses and Master's Reports

This project was conducted to analyze (model and simulate) and optimize an electric motor based drive system to propel a typical passenger vehicle in an urban driving environment. Although there are many HEV and EV type systems on the market today, this paper chose the Toyota Prius HEV system as a baseline using a brushless AC motor.

Although a vehicle can be driven many ways, a more standardized Urban Dynamometer Driving Schedule, UDDS, was chosen to simulate real driving conditions. This schedule is determined by the US Environmental Protection Agency, EPA, and is intended to represent the city driving conditions …

Electricity Sector Reform: Sourcing And Cost Management Of Electricity For Steel Manufacturing In Nigeria, Christopher Ndubuisi Okonkwo

Walden Dissertations and Doctoral Studies

In 2014, Lazard levelized cost of energy analysis model priced diesel powered systems at $0.225 – $0.404/KWh and a range of $0.165 – $0.242/KWh for gas-powered systems. The model gave a range of $0.28 – $0.33/kWh for diesel and a range of $0.14/kWh – $0.16/kW for gas fired. Nigeria has an abundance of gas reserves, but heavy gas flaring by oil companies perpetuates power failure across Nigeria. What has resulted is an unreliable electricity infrastructure and a high cost of alternative energy. The Electricity Power Sector Reform Act of 2005 started the reform process. Guided by decision theory, the purpose …
