In modern power systems, renewable energy has become an increasingly popular form of energy generation as a result of all the rules and regulations that are being implemented towards achieving clean energy worldwide. However, clean energy can have drawbacks in several forms. Wind energy, for example can introduce intermittency. In this thesis, we discuss a method to deal with this intermittency. In particular, by shedding some specific amount of load we can avoid a total system breakdown of...
Show moreIn modern power systems, renewable energy has become an increasingly popular form of energy generation as a result of all the rules and regulations that are being implemented towards achieving clean energy worldwide. However, clean energy can have drawbacks in several forms. Wind energy, for example can introduce intermittency. In this thesis, we discuss a method to deal with this intermittency. In particular, by shedding some specific amount of load we can avoid a total system breakdown of the entire power plant. The load shedding method discussed in this thesis utilizes a Markov Decision Process with backward policy iteration. This is based on a probabilistic method that chooses the best load-shedding path that minimizes the expected total cost to ensure no power failure. We compare our results with two control policies, a load-balancing policy and a less-load shedding policy. It is shown that the proposed MDP policy outperforms the other control policies and achieves the minimum total expected cost.

I investigate the depths of memory, the entanglement of personal recollections withcommunal knowledge (learned semantic information from media and society such as facts and social norms) and the changing perceptions of environments over time. Memories define us. Throughout life we are exposed to vast quantities of imagery through a variety of media and personal experiences. Over time our firsthand experiences and what we witness in film, print, photography, and the internet become...
Show moreI investigate the depths of memory, the entanglement of personal recollections withcommunal knowledge (learned semantic information from media and society such as facts and social norms) and the changing perceptions of environments over time. Memories define us. Throughout life we are exposed to vast quantities of imagery through a variety of media and personal experiences. Over time our firsthand experiences and what we witness in film, print, photography, and the internet become indistinguishable in our memory.My work recreates consequential scenes from my past through technical drawings and blended imagery while exploring the possibilities provided by the interaction of common knowledge and the ambiguous nature of memory.
