查询词典 grid current

Based on analysis of application deficiencies of these two mechanisms, some improvement advices are advocated.A unified on-grid pricing mechanism, with the consideration of costs of generators and send-out projects, step options, adjustment along with technology advancement and provincial differences is proposed to replace benchmark pricing mechanism. Key problems such as standard and levels of return rate, reasonable partition of interest during the construction period are discussed in the unified on-grid pricing mechanism. A modified investment cash flows statement based estimation method of on-grid prices is proposed in the thesis. Return rate of on-grid electricity price should be adjusted dynamically according to the capital asset pricing model.
