The invention relates to a user side
light storage integrated
system demand charge capacity configuration
software algorithm. The
algorithm comprises the following steps that
software inputting is performed, and a user annual time-sharing curve is obtained as computing input; 2, according to a user annual time-sharing load curve, the best photovoltaic configuration capacity and the
investment cost are calculated according to the photovoltaic capacity optimized configuration under local consumption, and the best capacity configuration and the
investment cost of a storage battery are calculated according to the battery type of an arranged
energy storage system, the DOD discharging depth, the battery efficiency and other information and the requirement for charging and discharging time of peak shaving; if a
user pays the capacity fee according to the needed
electric charge, the
electricity consumption in
daytime is larger than that at night, the maximum demand
occurrence time is short and shorter than 1 h, the maximum demand can be lowered through
stored energy, and the demand
electric charge can be lowered. According to
energy storage, the charging valley time at night is 0 a.m. to 8 a.m., and discharging is performed during maximum demand occurrence. According to discharging power, discharging can be performed is performed when the electric supply P is larger than target power P, and discharging is stopped when electric supply P is equal to Ptn*40%. According to the monthly income, Cin=(P set power-Ptn*40%)*40 yuan per month, and electric supply P=P load-P photovoltaic.
