电动车采用加速。下一代EVS将具有更大的电池容量,并且能够以更快的速率充电。新开发的高功率充电基础设施将提供高达350千瓦至今的七次,最常见的充电容量(50kW)。作为充电中心乘以支持快速增长的采用,支持电网的创新方法变得至关重要。

The early adopter market is becoming the mainstream market.EV销售额增长102%for June 2017, and automakers continue to respond to demand with market commitments. Volvo Car Corp. announced that all of its models launched after 2019 will be either electric or hybrids, Volkswagen AG is targeting 25% EV sales by 2025 and Toyota Motor Corp. will not sell any fossil fuel vehicles after 2050. The energy implications of a booming EV market are staggering. In 2014, the U.S. population drove 251 million cars. If we electrify half of those cars, vehicles alone will demand 688 terawatt-hours of electricity, equal to 18% of total U.S. electricity consumption in 2015.

The pressing question is how the power supply will meet this rising demand and fulfill the promise of the EV revolution. This will require the industry to support three initiatives:

1。Predict change and then act on the prediction.Demand leads supply, so it is critical to anticipate the number of EV adopters, the location and timing of adoption and which urban settings and transportation corridors will require charging infrastructure to meet EV demand. With this insight, utilities can evaluate specific distribution lines and plan for upgrades. Regulators can prioritize approaches to help finance upfront capital costs where the grid infrastructure is deficient. Technology integrators keeping pace with emerging technologies and approaches can design energy solutions for areas where sufficient power does not exist.

公用事业公司已经提出了这些预测。萨克拉门托市公用事业区和黑色&veatch最近研究了2030年在路上包括240,000 eV的分布式能源(DER)情景。他们发现没有负载管理,平均,高达17%(12,000)的服务变压器,平均估计成本为7,400美元,可能需要更换,因为主要与EV增长相关联。该评估允许SMUD计划并响应不断变化的条件。

2。管理der作为投资组合。客户拥有和控制DER技术存在前所未有的增长。DER包括分布式发电,能源效率,需求响应和能量存储,但预计EV将是网格上最普遍的和广泛的普遍存在。如果公用设施和利益相关者可以协作开发高级EV充电生态系统,则集成EV和其他具有现有电源,传输和分配资源的竞争灵活性会产生更大的网格灵活性。利益相关者必须同时考虑完全集成的群众电荷充电,储能和分布式的机会。

探讨DER对电网的影响,黑色和戒备和太阳能电力协会进行的采访五大U.S.公用事业。为了响应越来越多的DER互连请求,这些实用程序开始与演示阶段DER探索主动管理。一个实用程序已映射了所有客户级的DER安装,并测试了进料器自动分区保护计划,以提高各种负载/ DEL方案下的可靠性。通过大局,公用事业可以在未来维护可靠的电力,随着负载和变量的需求。

3.Bust Siloes for Cross-Industry Collaboration。每个行业的利益相关者可以积极influence the pace of EV adoption, the deployment of charging infrastructure, energy management and the provision of grid power. With collaboration, decision-makers can establish stakeholder participation rules and incentives so that the EV charging network reflects site-specific approaches and the larger program goals. In particular, collaboration of regulators and legislators is critical: either they can facilitate EV adoption, private investment and new revenue for the utilities or they can create barriers that stunt EV market growth. With cross-industry participation, technology integrators can unify planning and deployment across stakeholders and systems; balance competing interests among stakeholders; and ultimately establish operation, policy and technology platforms that prepare the U.S. grid for mass adoption of EV.
