Abstract

The present application discloses an energy storage configuration method, system, device, and readable storage medium, including: obtaining system parameters and historical operating data of each node, each branch, and each generating set in the target grid; The daily maximum operation data corresponding to the historical operation data of the item; according to the maximum intraday operation data and system parameters, calculate the daily active power flow of each branch under different guarantee rates, and determine the corresponding intraday power flow limit curve; according to each branch in different guarantees Determine the trajectory sensitivity curve and the corresponding absolute value mean value based on the intraday power flow transgression curve under the high rate; select the branch corresponding to the absolute value mean value within the target range as the dominant branch, and determine the energy storage node on the branch to be configured; calculate The energy storage power and the maximum charge and discharge capacity of the energy node are used to ensure that the corresponding branch to be configured does not exceed the limit of the power flow under the preset guarantee rate. This application ensures that the operation of the power grid has better new energy acceptance capacity and economy.

Description

technical field [0001] The invention relates to the field of power grid planning and operation, and in particular to an energy storage configuration method, system, device and readable storage medium. Background technique [0002] In the face of continuously growing energy demand and increasingly prominent environmental protection pressure, my country has put forward the goal of a high proportion of renewable energy supply, and vigorously develop new energy represented by wind power and photovoltaics. But at the same time, the uncertainty of new energy output poses a challenge to the safe and stable operation of the power system. Because energy storage technology can realize the transfer of new energy production and load demand from time and space, it has become an important means to solve the problem of uncertainty in new energy output. [0003] Therefore, in the planning and operation of the power grid including large-scale new energy power systems, how to realize the opt...
