6 FAQs about [Photovoltaic energy storage auxiliary service fee calculation]
What is the cost allocation scheme of VCG 1 Phase?
The cost allocation scheme of VCG 1 phase does not consider the initial investment cost of SES, and only reintegrates the income and expenditure of each user subject in the micro-grid system.
Does SES affect power purchase cost and power abandonment cost?
According to the data comparison before and after SES participated in the adjustment of load-shaping ability, the power purchase cost and power abandonment cost of all users decreased after the use of SES, and the incentive income of user 1 and 3 also increased from 0 before to 9101.71 yuan and 8345.17 yuan respectively.
Does energy storage configuration affect social welfare maximization (SWM)?
Based on the poor utilization ratio and high use cost of energy storage configured on the user side, the controllability of adjustable load and the rationality of energy storage configuration are two key points that need to be considered for social welfare maximization (SWM).
How to solve cost allocation problem based on SES?
The cost allocation is mainly based on the use of SES, users need to pay a certain fee when using SES, and SES will also generate a certain operating cost. According to the interaction between them, we use VCG mechanism to solve the cost allocation problem.
