Problems solved by technology
[0006] Because current batteries are only used to provide a single service, batteries are idle for many hours of the day
Since the current battery cannot be fully utilized, it is impossible for users to solve various power consumption problems to obtain greater benefits (that is, it is impossible to comprehensively consider how to reduce energy costs, reduce demand costs, and obtain feedback on demand response load reduction ), and cannot greatly reduce the burden on the power supply system of the power company during peak hours

A charge and discharge control apparatus and method are provided. The charge and discharge control apparatus decides multiple discharge time intervals and multiple discharge power values for an energystorage according to a predicted load curve and a peak shaving threshold and decides multiple charge time intervals and multiple charge power values for the energy storage according to the predictedload curve and a customer base line. The peak shaving threshold is between a contracted capacity and a peak value of the predicted load curve. A difference between the peak value and the peak shavingthreshold is not greater than a maximum discharge power of the energy storage. The customer base line is between the contracted capacity and a valley value of the predicted load curve. A difference between the customer base line and the valley value is not greater than a maximum charge power of the energy storage.
Description
technical field [0001] The invention relates to a charging and discharging control device and method. Specifically, the present invention relates to a charging and discharging control device and method for battery energy storage equipment (Battery Energy Storage System; BESS). Background technique [0002] Electricity charges charged by power companies to users generally include two categories, namely energy charge and demand charge. The electricity charge is the charge derived from the total electricity used by the user within a certain period of time (for example: one month's billing period), and its pricing unit is "kilowatt hour (kWh)", also known as "degree". With regard to electricity costs, power companies usually implement a time-of-day electricity price system (that is, set different electricity price rates for different time intervals), thereby guiding users to reduce electricity consumption during peak time intervals. In addition, the demand charge is the charge...
