摘要:

风力发电和光热发电在多数工业化国家中应用广泛,但风力发电存在不稳定和波动等问题。光热发电的热储存能力可以有效减少风力发电的不稳定性,因此建立了风力发电与光热发电联合运行的模型。其中联合运行策略用两阶段随机优化模型来表示,其目的是在考虑实时不平衡结算的情况下,将日前市场收入最大化。为了更加直观地展示该模型给电网带来的经济效益,分别建立了风力发电与光热发电独立运行和联合运行2种情况下的模型,并通过算例对两者的总收益进行对比。算例表明,风力发电与光热发电联合运行系统可以有效地缓解实时不平衡问题,并明显提高了收益。

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
