Influence of load management in distribution network on voltages and active power losses: Case study

Production of photovoltaic (PV) power plants depends on weather conditions which can cause sudden and often unpredictable variation in their output power. Balancing the production from renewable sources with consumption requires utilization of power plants with fast response or energy storage systems what causes considerable costs. In recent years, in terms of balancing, the emphasis is on the higher role of the consumers. In this paper computer model of the part of distribution network is used to simulate and analyze demand side load management (using air conditioner installed in households) in the distribution feeder considering PV power plant expansion scenarios. Three case studies are analyzed: first with low penetration of PV plants in distribution system, second with moderate penetration of PV power plants and third with high penetration of PV power plants. Influence of demand side load management on network voltages and active power losses is investigated.
