Abstract

The utilization of solar energy for electricity generation is increasing. But, because of the factor of the intermittent irradiance and ambient temperature so that the energy produced fluctuates and unstable. For PV connected to the grid, these power fluctuations affect system stability and frequency. To overcome this problem, several methods for PV power stabilization have been developed. One of them is the Constant Power Generation, where PV output power is limited to a certain power value so it can reduce PV power fluctuations. In this paper, the Dynamic Power Injection method is proposed as modification of the CPG method with energy storage batteries. In principle DPI similar with the CPG method that determines the power limit, but DPI operation include the active power management by charging and discharging action. The battery is using as energy storage when Power PV greater Power limit. On the other hand battery as an energy source for active power injection at Power PV less than Power limit. Thus the output power in each condition can be maintained as Power PV equal with P limit. In this research, DPI modules are built on Arduino controller-based and monitored with the thingspeak webserver. The experimental results of DPI can stabilize PV power fluctuation at it's setting power with an error of 5% and a 15-second time delay.
