摘要: 为准确评价固定上网电价(FIT)政策效果和优化FIT水平,提出了优化投资者决策行为的量化模型,研究了可再生能源产出的不确定性对投资者最优投资时间和装机容量的影响,同时以政策成本最小化的方式,优化政府完成预期装机部署目标时所需的FIT水平.实证方面,使用实物期权方法和最小二乘蒙特卡洛模拟,以中国近海离岸风电投资成本等参数,评价和优化了当前的FIT水平.结果表明,目前中国近海离岸风电的补贴水平0.137 USD/kWh不足以覆盖投资者产量波动带来的风险溢价,政府应将补贴水平提高至0.146 USD/kWh才可有效刺激投资.

Abstract: Based on the strategic behaviors of investor, this article presents a policy evaluation model in which a specific Feed-in tariff (FIT) level can be evaluated and optimized. The influence of uncertain generation from RES on the optimal investment time and sizing (capacity choice) of investor was evaluated by using the proposed model. Also, from the view of a policy maker, the optimal tariff level was determined in the way of minimizing the total burden on ratepayers to achieve RES goals. By dint of the current tariff of offshore wind in China, empirical studies through the least squares Monte Carlo method and the real option theory assess and optimize the current level of FIT. It is revealed that the current tariff level of 0.137 USD/kWh for offshore wind in China would not be enough to offset the risk premium resulting from the output uncertainty. Improving the tariff level to 0.146 USD/kWh could take effect to stimulate investment.

Key words: feed-in tariff, offshore wind investment, real option, uncertainty
