摘要

Abstract

To coordinate local green power absorption and key section power flow stability in high-penetration renewable grids

this paper proposes a source–grid coordination strategy integrating green power tracing and DC power flow sensitivity. A green power distribution matrix with a path priority coefficient is built to quantify green power supply paths and prioritise absorption

and a DC power flow sensitivity matrix is established for accurate grid regulation. A dual-objective optimisation model (minimising power flow volatility

maximising green power absorption) is formulated and solved via convex optimisation. Year-round simulations on the IEEE 11-bus system and Yancheng's actual grid verify the strategy effectively suppresses power flow volatility

raises green power absorption rate

resolves the dilemma of curtailing renewables for stability and offers a new optimisation method for high-renewable grids.
