摘要/Abstract

摘要：

泛在电力物联网鼓励各种分布式电源、储能以及电动汽车等大量新型电力设备接入配电网侧。随着可再生能源在配电网中的渗透率不断提高及电力市场逐步开放，电网投资主体趋向多元化，可再生能源接入电网的不确定性和各主体利益的协调问题日益突出。考虑区域配电网中不同分布式能源（DER, distributed energy resources）投资主体的利润，提出了一种泛在电力物联网形势下基于激励机制的最优运行策略，该策略能减少负荷波动和潮流倒送对电网的不良影响，为DER投资者提高了利润，算例证明了所提方法的有效性。

Abstract:

The ubiquitous power Internet of things encourages a large number of new power equipment, such as distributed power supply, energy storage and electric vehicles, to connect to the distribution network.With the increasing penetration of renewable energy in the distribution network and the gradual opening of the electricity market, the investment entities of the power grid tend to be diversified.The uncertainty of the access of renewable energy to the power grid and the coordination of the interests of various entities resources is increasingly prominent.Considering the profits of distributed energy resources (DER) investors in the regional distribution network, an optimal operation strategy based on the incentive mechanism in ubiquitous power Internet of things was proposed.This strategy could reduce the adverse effects of load fluctuations and reversed power flow on the power grid, while increasing profits for DER investors.The calculation example shows the effectiveness of the proposed method.

Key words: ubiquitous power Internet of things, distribution network, distributed energy resources, multi-investment entities, incentive mechanism
