研究目的
To minimize the power loss and stabilize voltage fluctuation when PV cells are connected to the power distribution line.
研究成果
The integration of MPC via PV-based VAR scheme and estimator forms a closed-loop control system, which successfully detects, estimates, and compensates the lost performance caused by disturbances and guarantees voltage constraint as demonstrated in the simulation study.
研究不足
The study focuses on a bidirectional, single branch distribution circuit. The applicability and performance of the proposed scheme in more complex distribution systems are not explored.
1：Experimental Design and Method Selection:
The study uses a model predictive controller (MPC) integrated with a photovoltaic (PV)-based volt-ampere reactive scheme. The nominal power load data from California independent system operator is used to simulate dynamics of the system with DistFlow equations. An estimator is developed to reconstruct the state variables and power loads from measurements.
2：Sample Selection and Data Sources:
The study uses a bidirectional, single branch distribution circuit for simulation. The nominal power load data is sourced from the California independent system operator.
3：List of Experimental Equipment and Materials:
The study involves PV cells connected to a power distribution line.
4：Experimental Procedures and Operational Workflow:
The MPC and estimator form a closed-loop control framework to quickly recover from undesired disturbances by changing the real and reactive powers provided by PV cells.
5：Data Analysis Methods:
The performance of the proposed scheme is demonstrated through simulation, showing reduction in power loss and stabilization of voltage within a desired bound.
