The invention puts forward a photothermal
power station with
electric heating devices and a modeling and operation optimization method of the photothermal
power station. A model is applicable to the independent operation photothermal
power station, a multi-energy complementary
system with
wind power, photovoltaic and photothermal power generation functions and other scenes, and multiple operationconstraints are considered and comprise a thermal
power balance constraint with hot salt tanks as nodes, a
thermoelectric conversion relation constraint of the
electric heating devices, a heat tank hourly heat accumulation
state constraint, a constraint that stored heat is equal to released heat in a calculation cycle, a
thermoelectric conversion constraint of a turbonator, a starting heat constraint and an
electric power balance constraint of a
steam turbine, a wind curtailment and photoelectric power constraint used for the
electric heating devices, and other constraints. The mixed integer linear optimization technology is adopted to solve the
optimization problem. By additionally installing an appropriate amount of electric heating devices in the photothermal power
station, the electricquantity curtailment of
new energy can be effectively reduced, the photothermal
electric energy production is increased, and the operation economy of the photothermal power
station and the multi-energy complementary
system is improved.
