“…The charging coefficient of the part of subsystems can be increased, and the discharge coefficient can be reduced when partial subsystems must be preferentially filled according to the dispatch plan. Power distribution must be conducted on the basis of the initial values of SOC according to (1). Power must only be redistributed without SOC feedback control after the corresponding subsystem is full.…”

Renewable energy sources, such as wind and solar, face several obstacles, including curtailment, where the generated energy exceeds local demand and production must be reduced because of limited transmission capacity. Simultaneously, consumer demand for large-capacity batteries is expanding given the recent rapid development of electric vehicles (EVs) and plug-in hybrid EVs. A batterycharging mode, in which discharged batteries are transported from battery exchange stations in high-load areas to wind farms, is proposed to alleviate curtailment. In this study, batteries store otherwise curtailed energy and smooth the wind power output simultaneously. The structure of the battery-charging device is discussed, and the concept of a battery-charging container is proposed. The control principle of the battery-charging management unit is presented with a simulation model constructed in the PSCAD/EMTDC environment. A case study is simulated, and the feasibility of the mode is analyzed considering the levelized cost and energy losses. Simulation results show that this mode is a feasible solution to alleviating wind curtailment and providing fresh impetus for developing EV battery exchanges.

“…The global electricity production from wind sources is estimated at about 300,000 MW for 2015 compared to the 60,000 MW in 2005 [2]. With the promulgation of the Renewable Energy Law in 2005 [3], the electricity production from renewable energy in China has grown rapidly [4]. Recently, it has been shown that wind power output is an intermittent energy resource [5].…”

Abstract:With the increasing contribution of wind power plants, the reliability and security of modern power systems have become a huge challenge due to the uncertainty and intermittency of wind energy sources. In this paper, a hybrid energy storage system (HESS) consisting of battery and supercapacitor is built to smooth the power fluctuations of wind power. A power allocation strategy is proposed to give full play to the respective advantages of the two energy storage components. In the proposed strategy, the low-frequency and high-frequency components of wind power fluctuations are absorbed by battery groups and supercapacitor groups, respectively. By inhibiting the low-frequency components of supercapacitor current, the times of charging-discharging of battery groups can be significantly reduced. A DC/AC converter is applied to achieve the power exchange between the HESS and the grid. Adjustment rules for regulating state-of-charge (SOC) of energy storage elements are designed to avoid overcharge and deep discharge considering the safety and the high efficiency of the energy storage elements. Experimental results on the test platform verify the effectiveness of the proposed power allocation strategy in DC/AC converter and battery SOC adjustment rules for regulating SOC levels.

“…On one hand, flexible network configuration and operation mode under distribution automation (DA) provide the great potential to improve operation efficiency and assets utilization resulting in less grid construction [4,5]; on the other hand, smart grid introduces large amounts of renewable distributed generations (DG) into the distribution systems. These DGs produce far less CO 2 than traditional thermal power, and may reduce power losses [6][7][8].…”

“…Efficiency and security is difficult to be balanced without proper management approach [4][5][6][7]. Although the problems aroused by DGs and electric vehicles have been studied in the research of Active Distribution Network (ADN) [8][9][10][11], on-line security assessment and control is rarely involved.…”

In this paper, a new Distribution Management System (DMS) framework based on security region is proposed. First, the concept of Distribution System Security Region (DSSR) is introduced. DSSR is capable to describe the N -1 security boundary of the whole distribution network, including the secure output range of DGs. This new theoretic tool provides a chance for the implementation of real-time security analysis and active controls in DMS. Second, this paper proposes and describes five security states for distribution system. Third, an upgraded DMS enhanced with DSSR is proposed, which consists of advanced security functions such as preventive and predictive control of the trajectory of operating points. Finally, a practical case is presented to simulate the proposed DSSR-enhanced DMS, in which both the security region of network and the output range of DGs are calculated. Typical security functions are also demonstrated. In conclusion, the new DMS framework aims to help operate the system closed to its security boundary in order to improve the efficiency significantly within same security standard. This work is beneficial for future low carbon distribution systems with high penetration rate of DGs.
