Core Viewpoint - The implementation of dynamic peak pricing is essential for enhancing the stability and economic operation of power systems with a high integration of renewable energy sources, addressing challenges related to fluctuating demand and supply [1][4]. Group 1: Current Challenges in Power Systems - The integration of renewable energy into the power grid presents new challenges for ensuring safe and stable economic operations, particularly during peak demand periods in summer and winter [1]. - Static time-of-use pricing mechanisms currently in place do not adequately reflect short-term supply and demand fluctuations in the power grid [1]. Group 2: Dynamic Peak Pricing Mechanism - Dynamic peak pricing differs from current peak pricing as it does not have a predetermined start time, allowing for adjustments based on real-time supply and demand conditions [2]. - This pricing model enables power users to be notified of high prices during tight supply periods, encouraging them to adjust their consumption patterns [2]. Group 3: International Examples - In the U.S., many power companies have adopted dynamic peak pricing, where regional dispatch centers predict tight supply conditions and notify users in advance [3]. - Most U.S. companies implement this pricing model primarily during winter and summer, with some allowing for dynamic pricing throughout the year [3]. Group 4: Domestic Developments - In China, many provinces still utilize fixed peak pricing, but some regions like Jiangsu, Anhui, and Guangdong have begun implementing a modified version that uses weather forecasts to determine peak pricing for the following day [4]. - The potential for demand response remains largely untapped among commercial users, and dynamic peak pricing could enhance load curve adjustments during peak demand or emergency situations [4].
