Embodiment Construction

[0050] The peak-shaving scheduling method of the energy storage power station in the power system proposed by the present invention comprises the following steps:

[0051] (1) Assume that the power system includes M thermal power units and N energy storage power stations, and establish an optimization model for peak regulation scheduling of thermal power units and energy storage power stations in the power system. The objective function of the optimization model is as follows:

[0052]

[0053]

[0054] Among them, F 1 In order to minimize the peak shaving scheduling cost, t is the scheduling period, is the deep peak shaving quotation of the mth thermal power unit in the power system in the time period t, obtained from the power system dispatching center, T V is the deep peak shaving period, is the bid-winning depth peak-shaving amount of the m-th thermal power unit in the scheduling period t, that is, the down-regulated active power of the thermal power unit, which ...

Abstract

The invention relates to a peak regulation scheduling method for an energy storage power station in a power system, and belongs to the technical field of power system scheduling. According to the method, a power system peak regulation scheduling optimization model comprising an energy storage power station to improve the peak regulation capability of the system is constructed, and meanwhile, the voltage deviation of each node is considered in the model to meet the requirement of system safety. The model takes the minimum system peak regulation scheduling cost and the minimum time sequence average value of the sum of squares of normalized voltage deviations of all nodes as multiple targets, and the considered constraint conditions comprise system constraints, unit constraints and energy storage constraints. The genetic algorithm is employed for solving the optimization model. According to the method, the energy storage power station participates in system peak regulation to improve thesystem peak regulation capacity, and the thermal power generating unit peak regulation pressure is relieved; meanwhile, the system safety and the electric energy quality are guaranteed through dispatching, and a certain reference effect is achieved for the energy storage power station participating in peak regulation.

Description

technical field [0001] The invention relates to a peak regulation scheduling method for an energy storage power station in a power system, and belongs to the technical field of power system scheduling. Background technique [0002] The "Guiding Opinions on Promoting the Development of Energy Storage Technology and Industry" issued by the National Energy Administration pointed out that energy storage is an important component and key supporting technology of smart grids, energy systems with a high proportion of renewable energy, and "Internet +" smart energy. With the intermittent and fluctuating grid-connected operation of photovoltaic and wind power, as well as the continuous reorganization and improvement of the grid structure, the safe and stable operation of the grid has been challenged. Applying energy storage to the power generation side, grid side and user side can Effectively alleviate a series of problems caused by the increase in the penetration rate of new energy....
