研究目的
To decrease the total grid purchase of power systems by applying static network reconfiguration under thermal and voltage constraints.
研究成果
Applying static network reconfiguration to the test system with two PVs gave minimum power consumption from grid. The study found that network reconfiguration is more beneficial when there are fewer PV locations, with the highest benefit observed at two PV locations (46.04% increase in power sold back to the grid).
研究不足
The study is limited to a specific test system and does not explore the impact of network reconfiguration on systems with a very high number of PV locations.
1：Experimental Design and Method Selection:
The study formulates the problem as a load flow aiming to minimize the total grid purchase. It uses a modified benchmark distribution system to demonstrate the effectiveness of static network reconfiguration.
2：Sample Selection and Data Sources:
The test system is a 12.66 kV distribution system with normally closed and opened switches, and eight potential sites for PV deployment. Load and PV profiles are from Chulalongkorn University, Thailand, and Provincial Electricity Authority (PEA).

List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The study investigates two time periods: at night when PV cannot generate electrical energy and during the day when PV can generate electrical energy. It analyzes different scenarios with varying numbers of PV locations.
5：Data Analysis Methods:
The study compares total losses and total grid purchase before and after network reconfiguration for each scenario.
