Bidding strategy for energy storage participation in the spot market based on an adaptive McCormick method
an energy storage power station participating in spot-market bidding is difficult to coordinate day-ahead schedules with real-time deviation-energy settlement
and that the associated bilevel model suffers from low computational efficiency due to cross-market bilinear terms
this paper proposes a bidding strategy for energy storage participation in the power spot market based on the adaptive McCormick method. First
a bilevel bidding model is established that incorporates day-ahead and real-time market clearing as well as deviation energy settlement
and a profit-risk trade-off mechanism based on conditional value-at-risk (CVaR) is introduced at the upper level. Then after reformulating the bilevel model into a single-level problem using the Karush-Kuhn-Tucker (KKT) conditions
the cross-market bilinear coupling terms between day-ahead and real-time markets cannot be eliminated through strong duality equivalence. To address this
an adaptive piecewise McCormick linearization method is developed
which transforms the original problem into a mixed-integer linear programming model through dynamic relaxation interval contraction and backtracking mechanisms
enabling efficient solution. Finally
case studies conducted on a modified IEEE39-bus system demonstrate that the proposed strategy improves the profitability of energy storage while achieving satisfactory computational efficiency and convergence stability.
