Electricity Retailers + Virtual Power Plants: The Golden Duo for Energy Transition Original | New Energy Power Exchange | April 1, 2025, 16:37 Electricity Retailers + Virtual Power Plants: The Golden Duo for Energy Transition Original | New Energy Power Exchange | April 1, 2025, 16:37 1. Why Must It Be "Electricity Retailers + Virtual Power Plants"? 1.1 Resource Aggregation: Solving the Fragmentation Challenge of Distributed Resources • Core Logic: ◦ In power systems where renewables exceed 40%, real-time balancing is needed to manage the volatility of wind and solar. ◦ Dispersed resources with varying ownership and control protocols render traditional dispatch models ineffective. • Case Study: CATL's "Energy Storage Cloud" Initiative: ◦ Model: Partners with private electricity retailers to integrate 1.2 million EVs (total capacity: 6GWh), monitoring vehicle status in real time. ◦ Tech: Vehicle-to-grid (V2G) Protocol 3.0 limits single discharge to ≤20% (ensuring user range). ◦ Results: Provides 500MW instant peak-shaving capacity for Zhejiang's grid in 2025, with EV owners earning ¥2,300/year and battery degradation <0.5%. 1.2 Dynamic Optimization: The Key Tool for Resolving "Supply-Demand Spatiotemporal Mismatches" • Core Logic: ◦ Renewable output and load demand are misaligned in time and space (e.g., midday solar peak in Northwest China vs. low afternoon demand in coastal regions). • Case Study: Tesla South Australia Virtual Power Plant (2025 Upgrade): ◦ Model: Collaborates with AGL to expand home battery systems to 12,000 households (total capacity: 360MWh). ◦ Tech: Autobidder algorithm + weather forecasting pre-charges/discharges batteries to balance fluctuations. ◦ Results: Solar curtailment drops from 4.7% to 0.9%, household bills cut by 40%, and payback period shortened to 4.8 years. 1.3 Market Participation: Unlocking the Commercial Value of "Dormant Resources" • Core Logic: ◦ Distributed resources face high standalone transaction costs; retailers aggregate them via VPPs for bundled trading. • Case Study: Tencent Cloud "Energy OS" Empowering Guangdong Retailers: ◦ Model: AI trading engine integrates 800MW of distributed resources, optimizing

SEAFOREST's flexible solar panels are suitable for installation on various roofs Solar power generation for factories and buildings, purchase price to be tripled, period to be shortened Economy November 9, 2024 17:30 [Members-only article] The Ministry of Economy, Trade and Industry will triple the amount per kilowatt-hour of power generation and shorten the period to about one-quarter of the current amount for the subsidy system for solar power generation operators. It will be implemented in fiscal 2026 as well. This will allow investment recovery in solar panels and other equipment to be completed in a short period of time, leading to the expansion of the introduction of renewable energy. The system is called the Feed-in Tariff (FIT) system, and solar power generation operators can purchase electricity at a fixed rate per kilowatt-hour if they generate electricity on the roofs of factories and buildings... 工場･ビルの太陽光発電、買い取り価格3倍に 期間は短縮 経済 2024年11月9日 17:30 [会員限定記事] 経済産業省は太陽光発電の事業者向けの給付制度について、発電量1キロワット時あたりの金額を現状の3倍程度に増やし、給付期間を4分の1程度に短くする。2026年度にも実施する。太陽光パネルなどの投資回収を短期間で終えられるようにして、再生可能エネルギーの導入拡大につなげる。 固定価格買い取り制度（FIT）と呼び、太陽光発電の事業者は工場やビルの屋根で一定規模以上の発電量があれば、1キロワット時あたり...
