发展电动汽车是减少对石油的依赖以及解决环境污染的有效途径。但是,大规模电动汽车无序充电会严重影响电网的稳定性,主要表现在电网负荷峰值升高、电网电压下降以及电网能量损失变大等方面。众所周知,对电网进行扩容改造将需巨大的成本,而智能充电无需对电网进行大幅度改造即可有效地解决这一难题。智能充电不仅能为电力运营商创造可观的经济效益,同时还能使电动汽车用户受益。智能充电主要分为集中式充电和分散式充电。集中式充电根据电网信息和电动汽车的充电需求规划电动汽车的充电策略。充电策略的制定主要以电网运行成本最小、电网能量损失最小、电网负荷方差最小等为目标。分散式充电主要在获取电网状态信息和电动汽车的充电需求后制定浮动电价以激励电动汽车用户避开用电高峰期。最后,文章简要介绍了在智能充电框架下电动汽车与可再生能源融合的潜力、智能充电对电池的要求以及相应的通讯网络构建等问题。 相似文献

The ‘Smart grid’ has been described as the ‘Energy Internet’, combining energy technology with information technology. The promise of the smart grid is to upgrade ageing energy infrastructure through the use of emerging technology. The resultant smart grid would improve efficiency, the ability to use alternative energy sources, responsiveness and security of the system. The need for creating a smarter grid is clear. Yet the traditional tool used by policy and other decision makers to rapidly advance technology product platforms, the technology roadmap, is proving ineffective due to the unique regulatory and market structure challenges of the smart grid. If the smart grid is important and its development constricted, then there is cause for concern. Today, most smart grid development teams are focusing their roadmapping efforts at the local and national levels. Yet regional roadmapping efforts can create higher quality and better integrated outcomes. A more advanced roadmapping technique is required for the effective and efficient management of the emerging smart grid technology product platform. Here, a case study approach utilizing the Pacific Northwest smart grid regional planning effort is utilized to generate an improved technology roadmapping technique, one that addresses the needs of emerging multi‐root technology‐based products like the smart grid. This roadmapping technique is designed to more effectively include the market structure and regulatory challenges inherent in the smart grid. The new roadmapping model integrates multiple technology, business and policy concerns. 相似文献

The economy, national safety, and health care are tremendously dependent on the faithful supply of power. The communication technology integration and sensors in power systems have been authorized as a smart grid (SG) that is revolutionizing the model of power generation, distribution, monitoring, and control. To know the Smart Grid compatibility, many problems are required to be directed. The safety of the smart grid is the most challenging function and very crucial difficulties. This paper proposed, a safe demand-side management machine deploying machine learning for the Internet of Things authorized phase is recommended. The propounded demand-side management (DSM) machine protects the effective energy use based on their preferences. A particular flexibility sample was proposed to manage incursion into the smart grid. Anelastic agent prognosticates swindling companies, the ML classifiers are utilized. Promoted power management and intermediate control companies are recommended for processing power data to improve energy usage. The proposed project's effective simulation is implemented to examine the efficiency. The outcome of the analysis discloses that the planned demand-side management (DSM) machine is less susceptible to the incursion and it is sufficient to decrease the smart grid's energy consumption. 相似文献

Recently, ZigBee Smart Energy profile has been developed for various smart grid applications, such as automatic metering, demand response, load control, power fraud detection, fault diagnostics, and distribution automation. In this paper, the performance of ZigBee has been evaluated in terms of network throughput, end-to-end delay, energy consumption, and packet delivery ratio in different smart grid environments, including an indoor power control room, an outdoor 500 kV substation environment, and an underground network transformer vaults. Overall, our performance evaluations show that the ZigBee is ideal to use for low-power and low-data rate smart grid applications not having very high reliability requirements and real-time deadlines. 相似文献
