Research and Application of Distributed Photovoltaic Flexible Participation in Power Grid Peak Shaving Technology Based on the Concept of Grading and Collaboration
摘要
Abstract
Distributed photovoltaics are experiencing explosive growth in multiple regions,and there is an urgent need for distributed photovoltaics to participate in automatic power generation control technology for grid peak regulation during scheduling and operation.The existing scheduling automation system's automatic power generation control is designed for traditional centralized power sources,and cannot adapt to the demand for distributed photovoltaic normalized participation in grid peak shaving from aspects such as system architecture,control strategy,and regulation performance indicators.To address this issue,this paper first analyzes the challenges brought by the development of new energy to the peak shaving of the power grid,and then deeply integrates the characteristics of distributed resources with the demand for regulation.It innovatively proposes a distributed photovoltaic automatic generation control technology route and system architecture based on the"hierarchical collaborative"idea.Based on this idea,the provincial and local two-level distributed automatic generation control strategy for peak shaving of the power grid is elaborated.For the first time,the total peak shaving demand calculation method,instruction allocation strategy,and transfer strategy when response rate is insufficient are provided.The regulation performance indicators for distributed photovoltaics are defined,and an actual control system is developed.Finally,the practical application of the method and system described in this article in provincial power grids is introduced,verifying the effectiveness and practicality of the method described in this paper.关键词
