Application of Nonlinear Model Predictive Controller for Ocean Wave Energy Conversion Systems

Creator:: Haider, Ali S.
Abstract:: This work addresses the application of Nonlinear Model Predictive Control (NMPC) to a class of ocean wave energy conversion systems in which the cost functional is not in a standard quadratic form, and the WEC model includes the nonlinear effects, such as the hydrodynamic viscous drag. The NMPC implementation is...

Design and Implementation of a Frequency Controlled Electric Hot Water Heater Retrofit Thermostat

Creator:: Johanesen, Mackenzie S.
Abstract:: This design of a Grid Friendly Electric Hot Water Heater Thermostat was built for the Electrical and Computer Engineering Senior Design course, ECE44x. The design enables hot water heaters to respond to imbalances in the grid seen through deviations from standard grid frequency by varying the power output to the...

Validation of Wave Energy Converter Models and the Development of Control Strategies in WEC-Sim

Creator:: So, Ratanak
Abstract:: When the term renewable energy is mentioned in a conversation, wind, solar, and hydro energy typically come to mind. However, there is one major resource that has remained mostly untapped: wave energy. Wind and solar power technologies are well established around the world but they cannot generate electricity all the...

Use of a model predictive control framework for optimal control of grid scale electrical energy storage in conjunction with a wind farm

Creator:: Antonishen, Michael P.
Abstract:: Over the last decade, wind penetration in the Pacific Northwest has increased rapidly. The variable nature of this massive new resource has increased stress on the hydropower resource to the point where system limits are currently being reached. In order to cultivate continued growth of the wind energy industry both...

Evaluating the seismic risk and resilience of an electrical power system

Creator:: Chalishazar, Vishvas H.
Abstract:: The Pacific Northwest is part of the "Ring of Fire," which is well-known for heavy seismic activity. Numerous active faults in the area have encouraged electric grid managers in the region to more deeply contemplate and proactively intervene to support grid resilience. This research introduces Monte Carlo (MC) based power...

Computing Substation Fragility as a Function of Seismic Component Failure

Creator:: Stark, William D.
Abstract:: The electrical grid of the Western Interconnection is vulnerable to earthquake damage, especially large-magnitude megathrust events, due to the unique seismic profile of the region. However, the size of the Western Interconnection makes it difficult to model seismic failure in electrical substations to the level of detail necessary to improve...

Experimentation of Synchronous and Variable Speed Small Scale Hydropower Systems

Creator:: Jackson, Elliott C.
Abstract:: Hydropower is the one of the oldest renewable energy technologies and is wrongly thought of today as having little room to grow. The opportunity for new hydropower capacity is immense through both technology advancement and run-of-river new stream reach projects. Despite the age of hydropower, a divide in opinion is...

Methods for short-term prediction of wind speeds in the Pacific Northwest Columbia Gorge wind farm region

Creator:: Davidson, James D.
Abstract:: Variable electrical generation (VG) sources such as wind farms are an increasing percentage of total electrical generation in the Bonneville Power Administration (BPA) balancing area and are starting to impact the ability of the regional balancing authority to control the electric grid. Wind farms are not dispatchable and challenge historical...

A motor-generator and supercapacitor based system for microgrid frequency stabilization

Creator:: Crispo, Richard F.
Abstract:: This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term...

A survey of power systems vulnerability and failures on the Pacific Northwest due to natural disasters with a focus on volcanic activity.

Creator:: Tafempa Messa, Winnie
Abstract:: Electricity is at the center of attention as today many essential systems (water, gas, communications, and the internet for example) and infrastructures depend on its continuity for their smooth functioning. On the other hand, electricity power networks have developed and became large, and highly complex technical systems, geographically extended, requiring...
