Abstract:

Under the goal of carbon peaking and carbon neutrality, the construction of new power system has transformed the traditional regulation and control mode of "source with load" to "source-load interaction". Considering the regulation and control ability of multi-types adjustable loads, it is of great practical significance to promote the participation of multi-types adjustable loads in the market, improve the operation efficiency of power system and promote the absorption of new energy. In this paper, the models of multi-types adjustable loads are firstly established to study their regulatory ability. Secondly, an optimal operation model considering multi-types adjustable loads access to distribution grid is established, and the model transformation is solved. Finally, the accuracy of the proposed model is verified by case analysis.

I. Introduction

In the context of green development, the development of new energy has become a global trend. With the rapid development of new energy, large-scale distributed power sources are connected to distribution grid, but its uncertainty and randomness also bring huge risks and challenges to distribution grid. In addition, the characteristics of distributed power sources relying on the weather have led to their unsatisfactory absorption rate [1] [2]. There have been a large number of studies on above problems, such as distributed energy storage system (DESS), demand-side management and a series of research, but it still cannot solve problems completely. More and more new-type loads are emerging, and their adjustability is attracting attention. In particular, the electric power market reform on electricity sale side and the promotion of new Internet technology, communication technology and intelligent power consumption technology have made the adjustable loads more widely attracted. There are studies show that exploring the potential load-side dispatchability through electricity prices or incentives to achieve peak shaving and valley filling is a win-win measure for the power system and the load side [3].
