摘要：

太阳能价值电价是解决分布式光伏发电引起供电成本分摊不公和电网收益下降问题的新思路。针对目前的计算模型未考虑电网不同运行条件下的供电成本变化问题,提出基于分时电价的加权太阳能价值计算方法。按峰、平、谷三时段典型化电网运行条件,讨论了相关参数的设置,建立了改进模型。新模型更好地计及了光伏发电与电网运行的时间一致性,能够更准确地反映光伏发电的价值。仿真分析验证了本方法的有效性。

关键词: 分布式光伏, 分时电价, 加权太阳能价值, 供电成本

Abstract:

Value of solar tariff is a new way to solve the problem of unfair allocation of power supply costs and revenue decrease of power grid company caused by distributed photovoltaic power generation. Because the existing model did not consider the change of power supply cost under different operating conditions of power grid, a weighted solar energy value calculation method based on time-of-use electricity price was proposed in the paper. The operation conditions of the grid were typificated as peak, flat and valley periods, the setting of relevant parameters was discussed and an improved model was established. The new model accounted more for the time consistency of photovoltaic power generation and grid operation, and could reflect the value of photovoltaic power generation more accurately. Simulation analysis were done, the results demonstrated the effectiveness of the proposed model.

Key words: distributed photovoltaic, time-of-use electricity price, weighted value of solar tariff, power supply costs
