The utilization of energy storage system (ESS) is an effective method for dealing with the randomness and variability wind power. Therefore, improving coordination between ESS power a direction worthy research. This study develops two-layer stochastic model predictive control (SMPC) smoothing on different time-scales. proposed optimization framework smooths by adjusting charge discharge hybrid ...

Due to the increasingly serious energy crisis and environmental pollution problem, traditional fossil energy is gradually being replaced by renewable energy in recent years. However, the introduction of renewable energy into power systems will lead to large voltage fluctuations and high capital costs. To solve these problems, an energy storage system (ESS) is employed into a power system to red...

Plug-in electric bus (PEB) is an environmentally friendly mode of public transportation and plug-in electric bus fast charging stations (PEBFCSs) play an essential role in the operation of PEBs. Under effective control, deploying an energy storage system (ESS) within a PEBFCS can reduce the peak charging loads and the electricity purchase costs. To deal with the (integrated) scheduling problem ...

The loss of distribution networks caused by various electrical motors including transformers and generators can significantly affect the efficiency economical operation power grid, especially for new systems with high penetration renewable energies. In this paper, potential using an energy storage system (ESS) reduction is investigated, where a novel two-stage method key-bus selection ESS sched...

Since renewable power is intermittent and uncertain, modern grid systems need to be more elegant provide a reliable, affordable, sustainable supply. This paper introduces robust optimal planning strategy find the location size of an energy storage system (ESS) feeders. It aims accommodate wind integration serve future demand growth under uncertainties. The methodology was tested in IEEE RTS-96 ...

Various attempts have been made to reduce carbon emissions in the energy sector as part of global net zero trends. Among them, interest use storage systems (ESSs) for efficiency is growing. Utilities intend improve investment and operating costs by reducing maximum peak leveling load. Many ESS-scheduling optimization techniques studied demand, balance load, or cost corresponding these two purpo...

Abstract Malaysia signed Paris agreement in 2015 as global response to climate change and committed lower the greenhouse gases emissions by 45% 2030. Under this national initiative, government planned a series of large scale solar (LSS) projects regulated Energy Commission. It is aimed achieve installed capacity 1 GW 2020. One main drawbacks for using energy intermittent issue power generation....

The integration of PV and energy storage systems (ESS) into buildings is a recent trend. By optimizing the component sizes operation modes PV-ESS systems, system can better mitigate intermittent nature output. Although various methods have been proposed to optimize size achieve online management in optimal interconnection between them has received less attention. In order maximize effectiveness...

The economic and environmental benefits brought by electric vehicles (EVs) cannot be fully delivered unless these vehicles are fully or partially charged by renewable energy sources (RES) such as photovoltaic system (PVS). Nevertheless, the EV charging management problem of a parking station integrated with RES is challenging due to the uncertain nature of local RES generation. This paper aims ...
