为解决省调全网调峰及输电断面控制、地区主变压器过载风险控制等省地不同的新能源控制场景需求,对省地新能源有功协同自动控制体系架构及策略开展研究。采用“省调-地调”与“集中-分布”协同技术路线,在省、地两级调度主站部署新能源自动功率控制模块,构建“1+

”全电压等级新能源有功协同自动功率控制体系。依托该体系进一步提出两类省地新能源资源双向协同支援策略,即地调将其管辖的可调资源聚合上送至省调,满足省调调节需求,地调也可针对本地主变压器

-1过载等紧急情况生成调节指令,经省调统一决策后下发至统调资源执行,全面提升电网平衡调节能力。通过某省、地两级调度的实际运行效果验证了所提体系及策略的有效性,保障了电网安全稳定运行及新能源最大化消纳。
To address the diverse requirements for renewable energy control scenarios at the provincial and local levels
such as provincial grid peak regulation and transmission section control
as well as local main transformer overload risk control
research has been conducted on the architecture and strategies of a provincial-local coordinated automatic active power control system for renewable energy. A coordinated technical approach combining “provincial dispatch-local dispatch” and “centralized-distributed” strategies is adopted. Automatic power control modules for renewable energy are deployed at both provincial and local dispatch master stations
establishing a “1+
N

X
” coordinated automatic active power control system for renewable energy across full voltage levels. Based on this system
two types of bidirectional coordinated support strategies for provincial-local renewable energy resources are proposed. Specifically
local dispatch can aggregate and transmit its adjustable resources to the provincial dispatch to meet the regulation needs of provincial dispatch. Meanwhile
local dispatch can also generate regulation commands in response to local emergencies
such as
N-
1 overload of main transformers. These commands are then uniformly decided upo
n by provincial dispatch and issued to unified-dispatch resources for execution
thereby comprehensively enhancing the grid balance adjustment capabilities. The effectiveness of the proposed system and strategy is verified by the actual operation effects of a provincial-local dispatch to ensure the safe and stable operation of the power grid and the maximum consumption of renewable energy.
