基于区块链社群思维的电力系统调频模型

Power System Frequency Regulation Model Based on Blockchain Community Thinking

电力系统频率调节对于维护电力系统稳定平衡具有重要作用,如何在调频辅助服务市场中对机组公平合理地补偿,激发机组参与调频积极度是电力市场改革亟需解决的问题。基于现有的区块链技术,提出一种具有去中心化,多方共识和代币激励特点的区块链社群思维。基于代币激励特点设计一种综合考虑全局调频效果和个体参与表现的调频积分,并以此建立具有去中心化特点的分布式调频系统频率响应模型。进一步,利用多方共识思维给出调频积分的结算流程,调动用户参与积极性并保证积分结果的真实可靠。算例部分验证了所述分布式调频系统的有效性,其能够有效完成系统调频任务和积分结算功能,并充分调动调频机组参与积极性,从而提升对分布式调频资源的高效利用。

Frequency regulation(FR) plays an important role in maintaining the power balance and stability of power systems. How to fairly and reasonably compensate generators and actively stimulate generators in the frequency regulation ancillary service market is an urgent problem to be solved by power market reforms. In this paper, a blockchain community thinking with decentralization, multi-party consensus and token incentive was proposed. Based on the token incentive feature,an FR credit was designed to integrate the global FR effect and individual participation performance, and then a frequency response model of the distributed FR system with decentralized features was established. Furthermore, the settlement process of the FR credit was designed by using multiparty consensus thinking, which can motivate generators to participate in FR and ensure the authenticity and reliability of the results. Case study verifies the effectiveness of the distributed FR system,which can effectively complete the system FR tasks and credit settlements, and fully mobilize the FR generators to enhance the efficiency of distributed FR resources.
