The most important task when introducing innovative methods and technologies Demand Side Management (DSM) in Grid System is prognostication, evaluation of performance and management of introducing innovative technology.

In the paper there are considered issues of modeling modes of control of Smart Power Grids based on the usage of the innovative method and device of Demand Side Management.

The paper will present research on increasing the efficiency of business processes in electricity grids, basing on the use of the innovative technology of demand side management in the framework of the conception of Smart Grids. Being presented for the introduction in smart grid system, the innovative method and device of DSM, are based on regulation of voltage in immediate vicinity to consumers.

Current work studies the wholesale electricity market of the Russian Federation. By historical standards this market emerged recently. The experience of its work is being accumulated, the problems affecting its efficiency being revealed.

The work considers questions of evaluating the efficiency of introducing innovative power saving technology on the example of the technology of NORMEL™, which allows to solve effectively the tasks of Demand Side Management. The offered simulation model, in the authors' opinion, will allow formalizing and making a more accurate evaluation of efficiency of introducing innovative technologies.
