Today in competitive power markets, with higher level of penetration of variable renewable energy resources, electric energy price becomes more volatile and uncertain. The integration of distributed generation into the distribution systems makes the load more volatile. It becomes more challenging for load aggregators to manage energy purchasing cost facing the higher price and load uncertainties....
This paper presents an optimization framework for a load aggregator with electric energy storage (EES) to determine its net imported power in electricity markets. The EES is operated by the load aggregator. The imported power from both day-ahead and real-time markets is a combination of the load and the EES power charging and discharging. The load aggregator's objective is to minimize its energy cost...
