Virtual power plant(VPP) is a fusion application of "Internet of Things +" and electric power industry, a new generation of smart grid control technology and interactive business model that aggregates and optimises "source, network, load and storage", which relies on modern advanced communication technology, carries out collaborative optimization control and market transactions, realizes multi-energy complementarity on the power side and flexible interaction on the load side, and provides forward-looking solutions for cracking the problem of clean energy consumption and low-carbon energy transformation. It relies on modern advanced communication technology to carry out cooperative optimisation control and market trading, realises multi-energy complementarity on the power side and flexible interaction on the load side, creates an active, convenient and sharing ecosystem for emerging market players, provides forward-looking solutions for solving the problems of clean energy consumption and low-carbon energy transformation, and helps the construction of "three types and two grids". This paper focuses on the problem of VPP, firstly, combined with the actual operation of the power grid, analyses the main needs in the process of power grid operation. Secondly, it analyses the characteristics of VPPs, the application scenarios of participating in grid operation, as well as the connection relationship with the existing grid scheduling and the market, and finally, on this basis, it looks forward to the operation prospect of VPPs in China and the problems that need to be solved.
Cet article montre l'interet qu'apporte la commande par platitude d'une Machine Synchrone a Aimants Permanents hautes vitesses, du fait d'un nombre reduit d'operations de son algorithme. La compacite des machines hautes vitesses entraine leur saturation magnetique dans certains regimes de fonctionnement, pouvant remettre en cause la propriete de platitude du systeme. Ces travaux montrent que la propriete.
