Abstract

The invention discloses an energy storage configuration method, system and device, and a readable storage medium. The method comprises the steps of obtaining system parameters and historical operation data of each node, each branch and each generator set in a target power grid; determining intraday maximum operation data corresponding to each item of historical operation data under different guarantee rates; according to the intraday maximum operation data and the system parameters, calculating an intraday active power flow of each branch under different guarantee rates, and determining a corresponding intraday power flow out-of-limit curve; determining a track sensitivity curve and a corresponding absolute value mean value according to the intraday power flow out-of-limit curve of each branch under different assurance rates; selecting a branch corresponding to the absolute value mean value in the target range as a dominated branch, and determining an energy storage node on a to-be-configured branch; and calculating the energy storage power and the maximum charge-discharge electric quantity of the energy storage node so that the corresponding to-be-configured branch does not generate power flow out-of-limit at a preset guarantee rate. According to the invention, power grid operation is ensured, and excellent new energy acceptance capability and high economical efficiency are provided at the same time.

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...
