Analysis of Demand Response in Distribution Network Scenarios with Photovoltaic Integration

Recently, advancements in technology, coupled with sustained policy backing, have led to a surge in the growth of distributed photovoltaic energy, which is a now integral component in the shift towards energy transition and sustainability. Connecting distributed solar power to the grid introduces a certain amount of active and reactive power. Daytime, with high light intensity, sees a significant active power output from solar systems, potentially raising grid voltage. Conversely, at night or with low light, the system's active power output is minimal, resulting in a minimal voltage impact on the grid. To optimize the use of distributed solar power and decrease overall carbon emissions, this paper suggests a demand-response strategy for the IEEE33-node system. The approach involves increasing load power during peak solar generation at noon and decreasing it at night, maintaining constant daily electricity consumption. This method demonstrates its effectiveness in shifting the power load to times of high solar generation.
