Does Power Spot price influence energy regulation?

The regulation results of aggregation (including power response, risks, and profits) show that the power spot price has become the dominant factor for the DESs aggregation group to make energy regulation. By using CVaR to quantify market risks, the economic profits obtained by the DES aggregation group can be ensured for real-time arbitrage.

Does a spot market reduce market power?

They find that the existence of a spot market mitigates market power and reduces prices. The authors of Wogrin et al. ( 2013) further elaborate on this by modeling the intensity of competition among producers using conjectural variations and investigating its impact on the resulting open- and closed-loop equilibria.
