地区电网与新能源无功电压协调控制

The Coordination Control of Reactive-Power and Voltage in the Regional Grid with New Energy Resources

随着新能源发电的快速发展,新能源电厂并网后的无功电压优化控制受到广泛的关注,文中结合新能源发电的特性以及目前成熟并广泛应用的地区电网自动电压控制系统,提出一种地区电网与新能源电厂无功电压协调控制的总体技术方案,详细阐述了协调控制原理及控制方案的实现。经实际系统的现场应用表明,上述技术方案和控制策略可行且有效,较好地解决了新能源并网的无功电压协调控制问题。

With the rapid development of new energy technologies, the coordination control of reactive-power and voltage in the regional grid with new energy resources is attracting an increasing attention. In this paper, combining new energy resources and widely used automatic voltage control system, we propose a technical solution to coordinate reactive-power and voltage in the regional grid. The engineering application results show that the proposed technical solution and control strategy is effective.
