摘要

该文基于大电网运行实践，聚焦于全网电力平衡资源的统一优化，研究新型电力系统的全网一体化电力平衡(integrated power balancing，IPB)机理。首先，构建IPB的数学模型，其中涉及“平衡区域”、“输电通道”和“输电路径”等关键要素。基于数学模型，推导IPB的网络方程，用以描述网络结构约束；其次，将电力平衡目标如电力供应和新能源消纳等与网络方程结合，推导作为IPB基本数学原理的动态方程，方程由4种过程形式组成——自然互济供电、成本互济供电、自然互济新能源消纳和成本互济新能源消纳；再次，将实际工程条件引入动态方程，分析总结工程实践用一体化电力平衡基础模式及其衍生的8种子构型；最后，通过实例验证所提理论分析的有效性和意义。

Abstract

Based on large grid operation practices and focusing on unified optimization of power balancing resources across the entire grid

the integrated power balancing (IPB) mechanisms of new type power system are studied in this article. Firstly

mathematical model of IPB is structured

which is illustrated with core factors such as "balancing zone"

"transmission channel" and "transmission routine". With the mathematical model

network equations for IPB are then deducted to characterize network structure constraints. Secondly

power balancing objects such as power supply and new energy consumption are brought with network equations

based on which dynamic equations are deducted as IPB's basic mathematical principles

which are composed of four process forms—naturally mutual aid for power supply

costly mutual aid for power supply

naturally mutual aid for new energy consumption

and costly mutual aid for new energy consumption. Thirdly

practical engineering conditions are brought into dynamic equations

with which 1 basic type as well as 8 sub-types of IPB for engineering practices are analyzed. Lastly

all the theoretical analysis is verified by examples to ensure its effectiveness and practical significance.
