Problems solved by technology

The aforementioned first and second types of technologies do not consider the time when the maximum load actually occurs, while the third type of method cannot deal with the problem when the actual load is different from the predicted situation
Therefore, although there are technologies that use storage batteries to reduce user peak loads, the effects of these technologies need to be further improved.

Abstract

The invention provides a charge and discharge control device and method. The charging and discharging control device divides a storage capacity of a storage battery into a reserve capacity and a plurality of preset discharge capacities corresponding to a plurality of dispatching time points, wherein each dispatching time point corresponds to a dispatching time interval and corresponds to a preset discharge power. The charging and discharging control device individually receives a load parameter of an electric circuit at each scheduling time point, wherein each of the load parameters carries a load power of the electric circuit. The charging and discharging control device further performs the following operations at each scheduling time point: (i) determining an actual discharge power provided by the storage battery to the power circuit according to a scheduling threshold value and the load power corresponding to the scheduling time point, and (ii) updating the reserve power according to the actual discharge power and the preset discharge capacity.

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". Regarding electricity costs, power companies usually implement a time-based electricity price system, setting different electricity price rates for different time intervals, so as to guide users to reduce electricity consumption during peak hours. In addition, the demand fee is the fee charged by the power compa...
