Abstract

The invention discloses a method for comprehensively optimizing energy storing power station planning and operating. The method comprises the first step of constructing a real-part matrix G and a virtual matrix B of a node admittance matrix used for carrying out load flow calculation according to network parameters of an electric power system and determining the upper limit value and the lower limit value of voltage of all nodes and the upper limit value and the lower limit value of all line power flow when the electric power system operates safely and stably, the second step of determining the upper limit value and the lower limit value of work output of a common electric generator, determining generating cost parameters of the common electric generator, determining the upper limit value and the lower limit value of the work output of a wind turbine generator or a wind power motor field and determining the penalty electricity price for draught fan fault according to the power source parameters of the electric power system, the third step of determining the capacity price, the power price and the average service life of an energy storage system and daily maintenance charge according to parameters of the energy storage system, the fourth step of determining the typical day wind power predicted data of the wind turbine generator or the wind power motor field, determining the day load data, determining the backup data of rotating of the electric power system and determining the transmission loss price of the electric power system according to scheduling operating data of the electric power system, and the last step of determining an inner layer optimization model and an outer layer optimization model according to the data collected in the first step, the second step, the third step and the fourth step.

Description

technical field [0001] The invention belongs to the field of new energy power generation and control, in particular to a comprehensive optimization method and system for energy storage power station planning and operation based on double-layer optimization theory (BLP) Background technique [0002] Since the beginning of the new century, the shortage of fossil energy and environmental pollution have become more and more serious, prompting the power industry to seek and develop renewable clean energy to replace existing chemical energy and optimize the energy structure. Renewable clean energy has gradually attracted people's attention. However, as the difficulty of power grid peak regulation increases year by year, and the construction of power grids in some areas is far behind the construction of power sources, the phenomenon of abandoned wind in wind farms in my country is becoming more and more serious, resulting in a huge waste of energy, and also for wind power generatio...
