Large penetration of intermittent renewable energy and complex loads in Active Distribution Network (ADN) has aggravated the fluctuation of voltage and increased power loss. Battery energy storage system (BESS) is a critical device in ADN, which are used to provide active power for the system. However, by connected with the grid using converter, battery has the ability to provide reactive power for...
In order to improve the penetration of distributed photovoltaic (PV) generation in distribution network, the issue of power fluctuations needs to be solved. In this paper, a real-time dispatch strategy for centralized energy storage station (CESS) is proposed. A double-layer structure of control strategy is designed, including the real-time dispatch layer and the power allocation layer, aiming to...
In order to improve the utilization of renewable energy in power system, it is needed to address the power fluctuation problem caused by grid interconnection of renewable energy power generation. A real-time dispatch method of energy storage station to smooth active power fluctuation is proposed in this paper. The real-time dispatch strategy is designed to smooth active power difference fluctuation...
To improve the security and reliability of a distribution network, several issues, such as influences of operation constrains, real-time load margin calculation, and online security level evaluation, are with great significance. In this paper, a mathematical model for load capability online assessment of a distribution network is established, and a repetitive power flow calculation algorithm is proposed...
