With world's increasing energy demand and growing environmental concerns, efficient utilization of energy is critical for sustainable living. Buildings are the major energy consumers, and a set of buildings are connected by distributed energy resources (DERs) such as chillers and boilers in certain building clusters, e.g., a school campus or residential community. Optimized operation of such building...
Sustainable development requires not only the use of sustainable energy resources, but also the efficient use of all energy resources. The latter should be reached by considering the concept of energy as well as exergy - the true magnitude of thermodynamic losses. Exergy describes the quality of an energy flow as the percentage that can be completely transformed into any other form of energy. Reduction...
With human environmental footprint exceeding the world's regeneration capacity by about 30%, conserving energy and reducing emissions and waste are critical for sustainable living. A new prototype of living is eco-communities which consist of a set of buildings and associated devices for energy generation, conversion, consumption, storage and recovery networks trying to be self-sufficient as much...
More and more wind generation is introduced to electricity markets. Yet, it is not clear how to conduct auctions with significant stochastic wind generation while avoiding dramatically increasing computational complexity. In this paper, the Markov process concept is innovatively used to model wind generation with transition matrices established based on the historical data. Wind generation is then...
In future power systems, the Smart Grid technologies will bring in a large number of new entities, which are different from those in the current systems in two major aspects: first, the entities are geographically distributed throughout the system with their detailed information not available to the system operator, and second, the entities tend to autonomously optimize their own benefits. In view...
Demand response is a reduction in the consumption of electricity by customers from their expected consumption in response to reliability or price triggered signals. Enabled by advanced metering infrastructure and other smart grid technologies, it is expected to be a crucial mechanism to compensate system uncertainties and the associated risks including those related to intermittent renewable generation...
