Assessment of Critical Load and Optimization Configuration Method for Small Hydropower Distribution Network with Integrated Hydro-PV-energy Storage
摘要
Abstract
To ensure the safe and stable power quality of critical loads in the small hydropower distribution networks and give the hydro-PV-energy storage a complementary role,this paper proposes a method for assessing the importance of loads and an optimization configuration method for integrating hydro-PV-energy storage systems into the small hydropower distribution networks.Firstly,the paper establishes a system based on two dimensions for evaluating load importance from the perspective of users,one is electricity utilization index and the other is electricity experience index.The G1-entropy weight method is used to quantify the importance of user nodes to determine critical loads,which are then considered as alternative nodes for integrating energy storage,effectively reducing the dimensions of the optimization configuration.Secondly,an optimization configuration model is built with the objectives of minimizing the full life cycle cost of hydro-PV-energy storage and the sum of voltage deviations.The normalized normal constraint method is introduced to solve the bi-objective optimization problem,yielding a uniform Pareto optimal solution set.Then,by calculating the comprehensive deviation function of each solution set,the optimal compromise solution is obtained as the best reference for optimization configuration.Finally,using an improved IEEE 33 node distribution network as a case study,the paper demonstrates that the proposed optimization configuration method can improve the voltage deviations of critical loads while increasing investor returns.关键词
