Abstract

With the continuous development of energy industry, the contradiction between supply and demand is becoming increasingly serious. In order to coordinate the contradiction between power system and distributed renewable energy, and deal with many challenges brought by new energy power to power system. We should fully exploit the value and benefits of new energy for power system and users. In this paper, a new urban virtual power plant system is proposed, which integrates distributed generation units, energy storage system and controllable load. It uses advanced data communication and coordinated control technology to realize the organic overall regulation and control of various types of distributed energy and load, to reduce the challenge of randomness and volatility of high penetration distributed generation to power grid operation and dispatching, and to alleviate the contradiction between supply and demand.

Highlights

  • As the basic industry of national economy, energy industry is the necessary premise to ensure the national strategic security, and an important guarantee to realize the sustainable development of economy

  • China's energy production and consumption are in the forefront of the world, there are a series of prominent problems in energy supply and utilization, such as unreasonable energy structure, low energy efficiency, low proportion of renewable energy development and utilization, and the level of energy security needs to be further improved

  • Based on the theoretical research of virtual power plant, a series of virtual power plant engineering demonstration projects have been carried out in foreign countries, such as "e-energy" project in Germany, pilot project of solar energy supply Technology Research Institute of Kassel University in Germany, EU virtual fuel cell power plant project, EU Fenix project, which are mainly aimed at achieving the goal of reliable grid connection of distributed generation and power market operation In the United States, virtual power plants are mainly based on demand response planning, and controllable load is the main component

Summary

Introduction

As the basic industry of national economy, energy industry is the necessary premise to ensure the national strategic security, and an important guarantee to realize the sustainable development of economy. The purpose of virtual power plant is to integrate all kinds of distributed energy, including distributed generation, controllable load and energy storage devices, and fully tap the value and benefits of distributed energy for power grid and users. Jiangsu, Beijing and Shanghai have carried out the practice of virtual power plant, the control object is translatable load, which can not fully cope with the huge impact of the rapid development and various types of distributed generation and controllable load on the safe and stable operation of power grid. Based on the existing foundation, this paper proposes a new type of urban virtual power plant system, which is connected with a variety of user side resources, and at the same time actively responds to the power grid dispatching signal to coordinate the supply and demand balance of the power grid, so as to realize the optimal allocation of various energy resources
