lately , Danish University of technology (DTU) The researchers announced that they have pioneered the application of quantum computing to power flow modeling of energy systems .

In this project ,DTU The work of researchers in the Department of wind energy and energy systems is focused on exploring the potential of current quantum computing in energy system power flow research .DTU The researchers say , Although they have proposed quantum power flow algorithm earlier , But these algorithms are only used for simulation and have not been tested on real quantum computers .

Now? ,DTU The researchers based their creation on “ Fast decoupling power flow ” New algorithm of method , At five different stations IBM Tested on a quantum computer , These include four publicly available systems and another larger quantum system . The purpose is to verify the calculation results and evaluate the scalability of the method .

DTU The researchers say , In all test cases , The quantum power flow converges to the same solution as the classical method , And because of the noise in the current quantum hardware , With classical convergence 5 Compared with , The new algorithm needs more than 30 Sub iteration . Besides , Because the larger quantum computing system is affected by noise , The number of iterations increases .

DTU The researchers point out that ：“ We have proven that , Current quantum hardware can perform power flow for small test systems , But scalability is still one of the main problems at present .”

Encouraged by this result , Researchers will carry out research ： Renewable energy system based on quantum computer （ Including intermittent wind and solar photovoltaic power generation ） Real time analysis of power grid stability . meanwhile , They will also explore the best application of quantum computing and classical computing in energy systems .

Person in charge of calculation of the project Brynjar Sævarsson say ：“ future , With the development of quantum computer , We will reshape the way power systems are calculated . Quantum computers have the potential to solve difficult problems , This means that we will develop safe and stable tools for renewable energy based power systems , We are now embarking on this work .”
