非对称信息下可再生能源并网机制设计

摘要

可再生能源并网实践中,不仅存在其发电产出与电力需求随机性的问题,而且并网补贴政策还受到电网成本信息非透明的影响.本文借助收益共享合约理论,通过将分享系数构造成电网边际成本的函数,调整发电方与电网的部分转移支付,建立非对称信息情景下的收益共享合约.进而基于电网成本显示激励机制理论,对可再生能源电力产出与需求的随机性及电网边际成本进行参数变动性分析,得到合约协调的供应链均衡.%In the practice of renewable energy grid-connection,there is not only the problem of randomness in power generation output and electricity demand,but also the effect of information opacity of power grid cost on the subsidy policy.Based on the theory of revenuesharing contract,this paper establishes a revenue-sharing contract under the scenario of asymmetric information by constructing the sharing coefficient as a function of the marginal cost of the grid and adjusting the partial transfer payment between the generator and the grid.A parameter variability analysis is then carried out regarding the randomness of power generation output and electricity demand as well as the marginal cost of the grid based on the theory of revealed incentive mechanism of power grid cost.Therefore,the supply chain equilibrium through contract coordination is obtained.
