Embodiment Construction

[0023] The present invention is a new energy acceptance capacity evaluation method based on time-series Monte Carlo simulation, including three parts: state selection, state evaluation, and result statistics, which are specifically divided into the following steps:

[0024] ●Status selection: Arrange the maintenance of the unit to form a sequential output model of different components of the system, including sequential load output, line operation / fault status sequence, new energy sequential output, hydroelectric unit sequential output, and thermal power unit start-up status. Among them, hydropower output is arranged according to the principle of making full use of hydropower and water volume.

[0025] ●Status evaluation: A system state sequence is formed based on the timing output of different components, and the new energy acceptance capacity analysis model is used to evaluate different system timing states. The goal is to minimize the operating cost, and the variable is the ...

Abstract

The invention discloses an evaluation method of acceptance capability of new energy based on sequential Monte Carlo simulation. The invention provides an acceptance capability analysis model, so that limiting factors of the acceptance capability of the new energy, such as peak regulation, frequency modulation and line power flow restriction, can be analyzed, and a weak link of a system can be recognized according to abandoned electric quantity of the new energy, which is caused by the different limiting factors. According to the evaluation method, an evaluation framework for the acceptance capability of the new energy based on the sequential Monte Carlo simulation is established, the time-dependent factors in the system, such as change of an operation mode, load fluctuation, new energy fluctuation, water and electricity output arrangement, component fault and unit maintenance, are considered, the evaluation indexes, such as the abandoned electric quantity of the new energy, the electric energy production of the new energy and the acceptance capability value of the new energy, can be provided for a planner, the water and electricity output is arranged according to a principle of fully utilizing the water and electricity quantity, the peak regulation effect of water and electricity is fully exerted, and furthermore, in comparison with the previous evaluation method, the evaluation method is more complete.

Description

technical field [0001] The invention belongs to the field of evaluation of new energy acceptance capacity, in particular to a new energy acceptance capacity evaluation method based on time-series Monte Carlo simulation, which evaluates the acceptance capacity of a main network for large-scale new energy from a planning perspective. Background technique [0002] The development of clean and renewable new sources is one of the effective solutions to environmental problems and energy constraints, and it is also the only way for human society to achieve sustainable development. In recent years, new energy power generation has developed rapidly, and the installed capacity has increased rapidly. Because new energy power generation is green, environmentally friendly and renewable, the grid should accommodate the power and electricity of new energy as much as possible. [0003] New energy generally has the characteristics of low energy density, wide distribution, intermittent and s...
