采取建立数学模型的方法,给出分布式电源的接入对配电网产生的影响因素,建立这些因素与网络损耗,电压偏差的函数方程。以系统总有功网损最小和电压水平最优为寻优目标

摘要随着现在一次能源的过度开采和环境污染问题的日益严重,绿色环保的能源形势成为现如今追捧的目标。传统发电方式对资源的巨大消耗和其带来的环境污染也一定程度上限制了电力行业的发展。所以开发利用新能源的分布式发电技术成为现在各国电力研究的首要方向。39880
本文借鉴学者专家在分布式电源优化配置研究方面取得的相关成果,并在其基础上进行分析研究。主要介绍了分布式电源的类型,特点还有其接入配电网之后对配电网运行产生的各种影响。采取建立数学模型的方法,给出分布式电源的接入对配电网产生的影响因素,建立这些因素与网络损耗,电压偏差的函数方程。以系统总有功网损最小和电压水平最优为寻优目标,确定分布式电源在配电网中最优接入位置的方法。并以IEEE33节点配电系统为算例,运用前推回推潮流计算结合粒子群算法对建立的数学模型进行求解。分析算例的结果以验证分布式电源接入方案的合理性。

 Abstract As the primary energy now overexploitation and increasingly serious environmental pollution problems, green energy situation become the target of nowadays popularity. Traditional way generating huge consumption of resources and the pollution to the environment to some extent also limits the development of electric power industry. So the development of new energy power generation technology as the leading direction of national electric power research now. Now using the new energy power generation technology by electric power industry, and the distributed power generation technology to the superiority of its aspects to become the development trend of the current power supply technology. 源`自<六:维*论-文>网/www.lwfree.cn
In this paper, draw lessons from scholars and experts in the study of optimal allocation of distributed power supply related achievements, and on the basis of the analysis. Mainly introduces the types of distributed power supply, the characteristics and its access to distribution network after the various impact on distribution network operation. To establish the mathematical model, the method of the influence factors of access to the distribution network of distributed power supply, set up these factors and the network loss, voltage deviation function equation. With the system total effective minimum network loss and voltage level optimal as the optimization goal, locate in distributed power distribution network optimal access methods. And IEEE33 nodes distribution system as the example, using the forward sweep power flow calculation combined with particle swarm algorithm is used to establish the mathematical model. Analysis of the results of numerical examples to verify the rationality of the distributed power access scheme.
