研究目的
To propose a methodology for optimal sizing of a Hybrid (battery and ultracapacitors) Energy Storage system for ramp-rate control in PV plants.
研究成果
Hybrid energy storage systems combining batteries and ultracapacitors can effectively control the ramp rate of renewable power plants, with potential cost savings over battery-only solutions, especially under stricter ramp-rate restrictions. The proposed optimization tool effectively finds the best configuration of the HESS based on uncontrolled output signals, ramp limitation, and cost characteristics.
研究不足
The study is based on a fixed size of the components of the system and uses a subset of days for simulations to reduce computational time, which may not capture all variability in PV output.
1：Experimental Design and Method Selection:
The methodology involves simulating the operation of different energy storage devices for ramp-rate control by calculating the Net Present Cost over the project life.
2：Sample Selection and Data Sources:
A real case study of a
3：2 MW PV power plant in Maldives is used, with data scanned every second. List of Experimental Equipment and Materials:
The study uses batteries and ultracapacitors with specified characteristics and costs.
4：Experimental Procedures and Operational Workflow:
The operation of the storage system is simulated in a time scale of one second for different combinations of decision variables to find the optimal configuration.
5：Data Analysis Methods:
The Net Present Cost is calculated for each configuration to determine the most cost-effective solution.
