Problems solved by technology

[0003] The existing technology has not realized the construction of a comprehensive evaluation system that combines steady state and transient safety and stability indicators
One of the difficulties hindering this research is that it needs to be realized through software simulation, which often means "non-automation" and it is difficult to adapt to the "variable" characteristics of renewable energy

Embodiment Construction

[0027] Such as image 3 As shown, this embodiment involves an implementation method of a renewable energy system planning scheme evaluation system. Based on the PSD-BPA power flow and transient stability simulation platform, mass production simulation data can be realized through automatic power flow generation programs and transient stability automatic simulation simulations. Based on the steady-transient automatic co-simulation, all indicators in the regional multi-renewable energy system evaluation system can be obtained, so as to comprehensively and comprehensively evaluate the rationality, advantages and disadvantages of the planning scheme and optimize it.

[0028] All the above-mentioned indicators include: security indicators, stability indicators, economic indicators and interaction indicators between the regional power grid and the main network.

[0029] The safety includes two underlying indexes, the line current carrying ratio μ and the node voltage deviation ν, re...

Abstract

The invention discloses a renewable energy system planning scheme evaluation system implementation method. The method is based on a PSD-BPA power flow and transient stability simulation platform. Stable transient automatic joint simulation under mass production simulation data is realized through a power flow automatic generation program and transient stability automatic analogue simulation, and all indexes in a regional multi-renewable energy system evaluation system are obtained, so the rationality, advantages and disadvantages of a planning scheme are comprehensively evaluated and optimized. According to the method, the planning scheme can be comprehensively and quantitatively evaluated from multiple perspectives in combination with the safety, stability, economy and interactivity of the regional power grid, and guidance is provided for access point selection, unit constant volume and the like of renewable energy system construction.

Description

technical field [0001] The present invention relates to a technology in the field of renewable energy utilization, specifically a method for realizing a renewable energy system planning scheme evaluation system based on steady-state simulation and simulation, which can be used to evaluate and screen alternative schemes for renewable energy systems, indicators Calculated values ​​can be used to guide flexible modification of the protocol. Background technique [0002] With the continuous increase of elements in the power grid, the difficulty of modeling and solving power supply planning has increased significantly. The system evaluation decision provides an effective idea for solving this kind of power planning decision-making problem involving complex factors, and has been widely used. Compared with classical modeling optimization, the rationality and significance of adopting systematic evaluation decision-making lies in: 1) The decision maker can incorporate multiple or ev...
