This extreme value is the global extreme value, which is the best relationship of photovoltaic penetration and energy storage configuration. The maximum update generation number maxgen, population size sizepep, and photovoltaic penetration e i is used as input quantity into the system.
When the photovoltaic penetration is below 9% (Take the load curve on August 2 as an example), the photovoltaic power generation is not enough to generate energy storage (the photovoltaic power generation is far lower than the load demand, so there is no energy storage, that is, no PV abandoning). The schematic diagram is shown in Fig. 9 below.
