Distributed PV accommodation strategy for cold chain logistics parks based on hierarchical risk management
摘要
Abstract
To address the collaborative optimization challenges of microgrids containing distributed photovoltaics(PV)in cold chain logis-tics parks,where the refrigeration systems require 24-hour continuous operation to maintain strict temperature control(-18℃±2℃)while PV output concentrates during 10:00-15:00 and logistics operations mainly occur in early morning and evening,this temporal mismatch between power demand and PV generation leads to severe PV curtailment.Proposing a scheduling strategy that balances PV consumption rate and operational economy.This strategy tackles the issues of high PV curtailment caused by strong PV output randomness and the com-plexity of multi-objective cooperative optimization.A tripartite collaborative architecture of"source-load-storage"is constructed.Typical PV output scenarios and their probability distributions are generated using the k-means clustering algorithm.Downside risk constraints are employed to quantify the cost fluctuation risk under these scenario probabilities,providing a continuous regulation space spanning from risk aversion to risk neutrality.A multi-objective optimization model is established to maximize the PV consumption rate and minimize the comprehensive operational cost.A dynamic-weight ideal point method based on the rate of change of the objective functions is proposed.An improved escape algorithm is designed to solve this model.Case studies demonstrate that under a defined risk regulation level,the park's PV consumption rate reaches 95.13%,and the daily operating cost is reduced to RMB 7 356,representing a cost reduction of 21.60%compared to pre-optimization levels.The results verify that the proposed collaborative optimization method can effectively en-hance distributed PV consumption capability and operational economy.It provides a viable solution and theoretical foundation for schedul-ing complex microgrids containing high-penetration renewable energy and thermostatically controlled loads.关键词
