Offering and bidding for a wind producer paired with battery and CAES units considering battery degradation.

This paper presents a stochastic framework for offering and bidding strategies of a hybrid power generation system (HPGS) with a wind farm and two types of energy storage facilities, i.e., compressed air energy storage (CAES) and battery energy storage (BES) systems. The model considers the participation of the HPGS in consecutive electricity markets, i.e., day-ahead (DA) and intraday markets. To better address the proposed trading strategy problem, the BES degradation cost is also incorporated into the model. Furthermore, a mechanism based on energy procurement from demand response resources (DRRs) in the intraday demand response exchange (IDREX) market for the HPGS is also established to offset unexpected energy imbalances effectively. The suggested offering and bidding strategy is formulated as a three-stage stochastic programming problem incorporating a risk-alleviating index, namely, the conditional value-at-risk (CVaR). Results from several simulations indicate considerable profit gain and risk reduction achieved by the suggested offering and bidding framework. • Operating model of a wind-compressed air energy storage-battery system is developed. • The impact of the intraday demand response exchange market is thoroughly analyzed. • Role of battery degradation cost in joint and disjoint operating models is studied. • A three-stage scenario-based architecture is suggested to cope with the uncertainties. • Joint operating strategy ensures economic betterment compared to the disjoint one.
