Decision-making Method for New Energy Added Capacity Based on Contact Partition and Critical Inertia Calculation
摘要
Abstract
To deal with the problem of system frequency instability caused by large-scale grid-connection of new ener-gy,a decision-making method for new energy added capacity based on contact partition and critical inertia calculation is proposed.First,a large-scale power system is divided into regions,the equivalent value of power grid in the area di-rectly connected to the research system is calculated,and the equivalent inertia of the research system is calculated ac-cordingly.Then,from the perspective of frequency safety constraints,the critical inertia is solved according to the lin-earization model of primary frequency modulation of synchronous units,and the maximum added grid-connected capaci-ty of new energy is calculated by combining the constraint that the equivalent inertia of the power grid is greater than the critical inertia.The different situations under requirements of decommissioning of synchronous units in the future and higher quality frequency operation of power grid are also taken into account.Finally,the rationality and correctness of the proposed calculation method for the added grid-connected capacity of new energy are verified by simulations based on the Power System Analysis Software Package.关键词
