Abstract

Abstract:

Wind power and concentrating solar power （CSP） are widely used to generate electricity in most industrialized countries.Though there are problems such as instability and fluctuation in wind power generation,the thermal energy storage capacity of CSP system can effectively reduce the uncertainty in wind power generation.Thus, a model for the joint operation of wind power and CSP systems is proposed.The joint operation strategy is formulated as a two-stage stochastic optimization model, aimed at maximizing the day-ahead market revenue in the case of real-time imbalance settlement.In order to intuitively understand the economic benefits of the model to power grid,the models of wind power and CSP under stand-alone operation and joint operation are presented.The total revenues under the two operation modes are evaluated by conducting comparative studies.Case studies show that the joint operation of wind power and CSP can effectively alleviate the real-time imbalance and obviously boost their revenues.

Key words: wind power generation, CSP generation, joint operation, imbalance settlement, economic benefits
