Public building participated grid optimization operation method

Abstract

The invention discloses a public building participated grid optimization operation method. The grid optimization operation method comprises the steps of S1, building a public building adjustable resource optimization operation control information base, wherein the information base contains all adjustable resources such as photovoltaic cells, wind power generation, EV and adjustable loads in public buildings; S2, establishing an adjustable resource optimization operation mode, and sending the adjustable resource optimization operation mode to the adjustable resources in the buildings, wherein the ith adjustable resource receives the notification and judges whether the optimization operation mode is allowed to be accepted or not; and S3, if not, updating the information base according to constraint conditions, if so, judging whether a multi-objective optimization objective is met or not, if so, performing an optimization operation according to the mode, and if not, continuing to update the information base according to the constraint conditions. Fluctuations of an output building overall load curve are enabled to be greatly reduced, an optimized load area is stable, and the difference between peak and valley is also obviously reduced.

Description

technical field [0001] The invention relates to the technical field of power grid operation, in particular to a method for public buildings to participate in power grid optimization operation. Background technique [0002] Energy conservation and emission reduction is a national strategic policy, and it is the only way to develop a low-carbon economy and maintain sustainable development of the national economy. As the power source of the national economy and the core element of the national energy strategy, electricity is the lifeblood of the national economy and the key areas and main force of energy conservation and emission reduction. With the sustained and rapid development of my country's economy and the increasingly prominent structural contradictions, the peak load of the power grid continues to rise, and the peak-to-valley difference of the power grid shows a trend of gradually expanding. Safe and stable operation of the power system. In particular, public buildings...

Problems solved by technology

However, research on flexible and schedulable resources such as air-conditioning loads, lighting loads, electric vehicles, distributed energy, and energy storage in public buildings focuses on air-conditioning load forecasting, unilateral control of lighting, and research on charging and discharging models for electric vehicles. The research on the optimization control technology of flexible resources in the scenario is relatively single, mainly focusing on the improvement of building energy efficiency, less consideration is given to multi-objective scenarios such as the interaction between building and power grid demand, lack of research on complementary characteristics between adjustable resources, and less analysis of optimal combination models
