Development of Electricity Demand Forecasting System in Korea Considering the Volatility of Photovoltaic Power Generation

With the accelerating global growth of renewable energy sources, electricity load forecasting systems are undergoing significant structural and methodological transformations. South Korea is experiencing a paradigm shift driven by the increasing penetration of non-metered solar photovoltaic (PV) generation, which introduces significant volatility and complexity. Although actual electricity consumption (hereinafter "Total Load") increases, the observable grid-based demand (Market/System Load) may appear to decline due to the self-consumption and injection from distributed PV systems, especially those that are not measured in real-time by the market
