Optimal Allocation of EG in Distribution System Using Genetic Algorithm Technique

The interconnection of Embedded Generation （EG） in a distribution network would change the radiality of the convention power flows in the system. Instead of helping to reduce the system losses, it also improves the quality of the overall system network. However, improper allocation and sizing of its interconnection to the system could oppositely change those advantages. The total system may experience higher losses and instability. In this paper, a new technique to determine the optimal allocation of EG in distribution system by using Genetic Algorithm （GA） technique is proposed. The effectiveness of the technique is demonstrated using IEEE-69 bus distribution test system and simulated in MATLAB.

对低输量下老油田原油销售的思考

X油田原油60%通过管道销售至下游炼厂,40%就地销售油田所属炼厂。随着X油田原油产量逐年递减,原油销售出现困难和挑战,输油管道安全存在风险,下游炼油加工存在困难等,因此,为确保油田原油生产后路畅通,建议停输隐患管道,努力实现原油就地加工,实行原油分质分销,精益原油销售管理等,确保原油效益及销售顺利进行。
