Ebisa started his PhD project in February 2010 and his study focuses on investigating how the electricity grid integrating distributed utilities (such as distributed generators and storage units) can be optimized.

With the dual concerns of climate change and energy security, countries are paying attention to sustainable energy developments for renewable and green energy as well as efficient usage of energy. As a result, varieties of distributed power generation systems such as photovoltaic solar systems and wind turbines are expected to achieve significant levels of penetration into the power grid. Whereas the conventional power grid relies on highly controllable supply, some of the distributed sources are stochastic in nature thereby becoming source of variability on the power system. Moreover, the new technologies such as the heat-pump and the electric cars will increase the variability in the demand side. The variability affects the stakeholders in the power system one way or another, and could be effectively addressed by collective approaches involving all the stakeholders.

Accordingly, Ebisa plans to address the following research question:

• What is the optimal architecture of the network of the stakeholders in the electricity grid that optimizes the electricity power system?
• How can the distributed utilities (generators and storages) in the neighborhood be optimally integrated into the grid?
• What is the optimal demand-response technique for the optimal consumption of the electric power in the context of distributed utilities?
