摘要
研究了协调控制策略采用数字量开关切换的控制方式,以净负载为判断准则,假设各个子系统放电条件具备,根据负荷及客观的硬件情况,分别按照风、光、蓄、柴的顺次序与逆次序启停系统;从功率平衡的角度出发,归纳总结出复合系统的四种工作模式,分析得出在不同的天气情况、负荷情况及蓄电池工况时,多能量源之间的功率分配及运行模式切换律。该策略能有效地保证系统运行的稳定性,同时也为多能量源复合系统的分析提供了一种新的思路。
A kind coordinated control strategy was introduced applying digital switch control method. Assuming that each subsystem met the discharge conditions, this control method took the static load as a criterion; the sequence for starting the system went as wind, solar, radiation, batteries, and diesel engines while stopping was in reverse order. Base on the power balancing theory, four operation modes were inferred for this strategy system, which took different weather conditions, load conditions and battery conditions into account. The main idea for this strategy system was to guarantee the stability of hybrid system and provided a new method for the analysis of the complex system of multi-energy source.
