Embodiment 1

[0043] Such as Figure 1-3 As shown, the load control method for suppressing fluctuations in distributed power sources according to the invention of this example includes the following steps:

[0044] (1) Determine static load information and establish a static load model;

[0045] (2) Determine the output power of distributed power sources;

[0046] (3) Determine the static load voltage setting value;

[0047] (4) Track the output power of distributed power sources.

[0048] The static load in the step (1) is the residential load in the distribution network; the static load information includes the static load value, the proportion of the constant impedance load, and the proportion of the constant current load, to establish a static load model.

[0049] The model in the step (1) is:

[0050]

[0051] Among them, P and Q are active power and reactive power respectively; P n , Q n , U 0 Respectively, load active power, reactive power, and bus voltage amplitude during steady-state operatio...

Abstract

The invention relates to a load control method for stabilizing fluctuations of a distributed power supply. The load control method comprises the steps of: determining static load information, and establishing a static load model; determining output power of the distributed power supply; determining static load voltage set value; and tracing the output power of the distributed power supply. The load control method traces output of the distributed power supply through changing load magnitude by adjusting voltage, so as to reduce even eliminate adverse effects of output power fluctuations of the distributed power supply on a power grid. The load control method focuses on active and reactive joint optimization of the power system, has broad application prospect, and has a certain guiding significance to the intelligent development of the power grid.

Description

Technical field: [0001] The invention relates to a load control method, and more particularly to a load control method for suppressing fluctuations of distributed power sources. Background technique: [0002] With the development of economy and society, countries all over the world have an increasing demand for clean energy. The power industry has a trend of transition from the traditional centralized power supply mode to the centralized and decentralized power supply mode. Distributed power sources rely on their environmental protection and commercial benefits. And the advantages of national policies are becoming more and more widely used in the power system. The application of distributed power sources avoids the construction of new transmission lines and large-scale power plants, so it is a cost-effective means to improve the reliability of the power system, and it uses renewable energy to generate electricity, alleviating the energy crisis and improving energy security .
