Abstract
Flexible operation is a significant feature of active distribution network (ADN) with deep integration of distributed green power. In this paper we propose a source
grid and storage coordination planning method considering flexibility for ADN. Multiple time scales flexibility evaluation indexes system for ADN is constructed with long term planning and short term operation taken into account. It encompasses various dimensions of power regulation and grid regulation
including different levels of periods
feeders and network. A source
grid and storage multi-objective two-layer planning model is proposed considering flexibility. The upper layer makes decisions on multi-objective planning scheme based on annual comprehensive cost and long-term flexibility
while the lower layer optimizes the daily operation of each component to improve the satisfaction of operating costs and short-term flexibility. The technique for order preference by similarity to ideal solution is employed to handle multi-objective planning. The variable encoding and model solving strategy are developed based on harmony search and particle swarm optimization algorithm. Finally
the rationality of the planning scheme and daily operation mode is demonstrated through am illustrative example of six-feeder ADN
thereby validating the effectiveness of the proposed indexes based on the composition analysis of the flexibility indexes.
