Price-based demand response enters a new era, but utilities and regulators still need to verify its potential

Price-based demand response (PBDR) guides users to change electricity consumption behavior through price signals and is seen as a complement to traditional load control. Research by Lawrence Berkeley National Laboratory shows that its cost-effectiveness depends on a complete analysis of participation rates and load reduction factors. However, utilities and regulators point out that planning models often underestimate its value and lack support from large-scale operational data. This article synthesizes perspectives from LBNL research, EnergyHub, Xcel Energy, MPSC, SRP, APS, and other organizations to explore PBDR's shortcomings in planning, utility concerns, and pathways to implementation.

2024年PJM展望:容量市场、电厂退役与输电规划面临艰难抉择

据关键利益相关方与行业顾问分析,PJM互联公司今年面临的首要议题包括容量市场改革、电厂退役以及新型输电规划范式的建立。这些议题相互关联,共同考验着电网运营商的应对能力。其中,Talen Energy计划退役的Brandon Shores电厂(1282兆瓦)被视为对系统稳定性的最大潜在冲击,PJM已为此推进近8亿美元的输电项目并拟签订可靠性必须运行(RMR)合同。同时,容量市场改革在FERC部分批准后进入“2.0”阶段,而输电规划正从被动响应向基于情景的长期规划转变。

Utilities and Analysts See New Tools to Smooth Renewable Integration as 2024 Buildout Looms

Engineers and utilities are preparing for a 2024 boom in clean energy integration, driven by Biden administration goals and funding. With rising penetrations of variable wind and solar, new management approaches—such as DERMS, grid-enhancing technologies, and grid-forming inverters—are emerging to maintain reliability. Xcel Energy, Eversource, and others are testing these tools, though regulatory and cost hurdles remain.

随着可再生能源可靠性担忧上升,分析师称升级逆变器刻不容缓

随着风电、光伏等逆变器资源(IBR)渗透率提升,电网可靠性面临挑战。NERC与ESIG工程师强调,构网型逆变器(GFM)能主动调节频率与电压,替代传统同步机组,但美国缺乏统一标准。专家建议通过电池储能系统先行部署GFM,并加快试点与标准制定,以避免可靠性事件频发。

Can ERCOT's 'Connect and Manage' Model Accelerate and Cut Costs of Grid Interconnection?

The Federal Energy Regulatory Commission's July order aims to ease the generator interconnection backlog, but stakeholders and officials are eyeing ERCOT's 'connect and manage' model as a potential template for reform. This article examines how ERCOT's approach differs from the traditional 'invest and connect' framework, its benefits in speed and cost, and the operational and planning concerns raised by grid operators.
