基于最优潮流的分布式电源协调控制研究
摘要:分布式电源作为一种形式广泛、储量丰富、清洁高效的能源，能够很好地解决现有的能源短缺、环境破坏、资源配置等多种问题，且具有良好的经济性，已成为未来电力系统建设和能源系统发展所必须要全面考虑的重要部分；但是在分布式电源并网运行巨大优势的背后，还存在着许多诸如负荷预测、潮流变化、电能质量、功率波动等挑战和问题。提出一种配电网对于接入分布式电源的协调控制技术，将配电网的运行成本作为目标函数，在对负荷预测和分布式电源出力预测的基础上，以及最优潮流及其相关的约束条件下，采用序列二次规划法、内点法及遗传算法3种优化方法进行仿真，得到目标函数的最优值和相应的分布式电源的出力情况；通过对3种不同算法的比较发现，序列二次规划法能够更加有效地完成目标函数的寻优，可快速收敛，其有效支持了配电网对于分布式电源的协调控制技术。
Abstract：As a clean and efficient resource which has a wide variety of sources and a efficient using, distributed generation has a better way to solve the energy shorting, ruining the environment, resource allocation and other problems, and has good economy, which has become a important part of the building of future power systems and the development of source systems. But there still are some challenges and problems behind the huge benefits of distributed generation connecting to the grid, such as load forecasting, power flow variation, power quality, power fluctuation, etc. This paper proposes a coordinated control technology of distributed network to the connecting of distributed generation, which takes the operation cost as the objective function, and on the base of predicts of load and the output of distributed generation, according to the optimal power flow and the constraints, uses three optimal methods including the sequential quadratic regulation, interior point and genetic algorithm for simulation to obtain the optimal value of the objective function and the output of the corresponding distributed generation. Through the comparison of three different algorithms, the results show that the sequential quadratic regulation method can more effectively complete the optimization of the objective function and has quick convergence, which can effectively support the coordinated control technology of distribution network for distributed generation.
