本地能源市場 (LEM) 以實現更大的可再生能源部署、電網穩定性和更高的投資回報率Local Energy Markets Can Expand Deployment of Renewables, Stabilize the Grid, and Increase ROI |
||||||
本地能源市場 (LEM) 是一個受地域限制的自動化電力交易平台。自動化的 LEM 平台促進了多個買家和賣家之間的點對點 (P2P) 或第三方聚合器交易，目的是平衡電網特定部分的供需。此外，增加電池儲能係統的使用可以顯著減少電網進出口。因此，存儲顯著減少了 LEM 和電網之間的交易數量，有助於增強電網穩定性。
本報告探索本地能源市場 (LEM)，審查 LEM 功能，通過 LEM 提高電網靈活性，促進 DER 集成，並使投資者能夠實現更高的投資回報率。我們提供有關機會的信息。

地方能源市場機制（LEM）
DER 集成的增加帶來了重大的輸配電挑戰
- 隨著滲透率的提高，可再生 DER 可能會擾亂正常的經濟分配並導致淨負荷鴨曲線
設計良好的 LEM 有助於消除鴨曲線並減少清潔能源
- 允許 DR 交易可以實現基於市場的減少
- 動態相位切換可穩定配電網絡並實現基於擁塞的緩解
LEM 為產消者和分銷商帶來經濟效益
- LEM 抵消了電力支出對電網靈活性的影響
- LEM 可以推遲網絡容量升級
LEM 試點案例研究提供了重要的經驗教訓
- 美國：Brooklyn Microgrid
- 德國：Pebbles Project
- 荷蘭：Hoog Dalem Stedin Pilot Project
- 英國：Cornwall Project
LEM 的引入，在適當的指導下，將加速能源轉型
A local energy market (LEM) is a geographically constrained, automated platform for trading electricity. The market platform is composed of physically proximate consumers and producers of electricity-prosumers-who trade and consume locally-produced energy from distributed energy resources (DER) using the existing distribution network.
An automated LEM platform facilitates trading-either peer-to-peer (P2P) or through third-party aggregators-between multiple buyers and sellers with the goal of balancing supply and demand in a particular part of the distribution grid. Additionally, the increased utilization of battery energy storage systems significantly reduces grid exports and imports. In turn, storage substantially reduces the number of transactions between the LEM and the distribution network, contributing to enhanced grid stability.
This report reviews LEM functionality and describes opportunities for using LEMs to provide greater grid flexibility, facilitate increased integration of DER, and help investors realize greater ROI

How Local Energy Markets Work
Increased DER Integration Raises Significant Transmission and Distribution Challenges
- At Greater Penetrations, Renewable DER Can Disrupt Normal Economic Dispatch, Causing a Net-load Duck Curve
Properly Designed, LEMs Can Help Solve the Duck Curve and Reduce Curtailment of Clean Energy
- Permitting DR Trading Reduces Market-based Curtailment
- Dynamic Phase Switching Stabilizes Distribution Networks and Reduces Congestion-based Curtailment
LEMs Produce Financial Benefits for Prosumers and Distribution Utilities
- LEMs Offset Utility Expenditures on Grid Flexibility
- LEMs Can Defer Network Capacity Upgrades

- Germany: Pebbles Project
- Netherlands: Hoog Dalem Stedin Pilot Project
