Abstract:

The integration of renewable energy sources into electricity distribution networks leads to environmental benefits such as lower pollutant emissions and reduced dependence on fossil fuels, and is a key ingredient of the smart grid vision. The chief challenge however is that renewable energy sources are non-dispatchable and highly intermittent. Accounting for the uncertainty of renewable energy sources is thus key to efficient management of distributed energy resources, which include electricity generators, energy storage units (batteries), and programmable loads. The first part of this talk considers smart distribution systems featuring a potentially large number of end-users with programmable loads as well as photovoltaic (PV) generation units, and the aim is to minimize system thermal losses and maximize end-use satisfaction, while maintaining voltage at safe levels. To this end, a stochastic power management scheme to optimize the demand response schedule of programmable loads as well and the reactive power generation or consumption by PV units will be presented. The second part of the talk focuses on small-footprint power systems with distributed generation from renewable as well as conventional energy sources, and distributed storage. To address the intermittency of renewable energy sources, robust energy management methods to maintain the supply-demand balance and minimize the system net cost will be presented.
