Energy Management in a Prosumer Installation Using Hybrid Systems Combining EV and Stationary Storages and Renewable Power Sources

Abstract

Modern consumer installations can be equipped with renewable power sources (RESs) and stationary energy storage systems (ESSs). In addition, electric vehicles (EVs) are expected to become part of such installations in the not-too-distant future. The paper presents the control strategy that allows for efficient energy management and the option of EV “fast-home” charging. The novelty of this approach includes the use of the “time-dependent energy storage” (EV battery) together with ESS and PV sources with the focus on prosumer benefits. All goals can be achieved without the need for extensive expenses in the home electric infrastructure. To enable the synergy effect, it was necessary to develop a controller algorithm that uses the operating status of the prosumer infrastructure (current power generation and consumption), the state of charge of both the stationary storage and the EV battery, and the possibility to control the EV drive inverter during the parking state. The paper presents a developed simulator built in the PSCAD environment and the simulation results.

Simulation of Electric Vehicle Charging Points Based on Efficient Use of Chargers and Using Recuperated Braking Energy from Trains

“…The stability of local electricity distribution grids (EDG) by supplementing energy storage systems (ESS) or a new source of renewable energy was addressed in [49][50][51][52][53][54]. Both the ESS and the new energy source should be built as close as possible to the EV charging point [55].…”

“…Both the ESS and the new energy source should be built as close as possible to the EV charging point [55]. Due to the nearby installation, there are no frequently long-distance energy transmissions that would overload the grid and also contribute to energy transmission losses [10,53]. In addition, the benefits of ESS include smoothing of peaks in the consumption pattern and accumulation of energy produced from RES that is not directly consumed [54].…”

Renewable Energy Electric Sources Chance in Multilevel Cellular Communications Networks

“…All possible solutions differ in the specific fields of applications, delivering different types of energy with various time and space distribution, power density, reliability and production costs. Additionally, successive de-carbonization technical aspects of renewable sources with grid cooperation must be successively addressed as well as the cheap and effective energy storage systems shall be introduced [11]. Expected share of each mentioned energy source in the future global energy market is shown in Fig 1, with remarkable expected explosion of PV and growing of wind in the future decades.…”

Integral input-to-state stability of switched delayed systems with delay-dependent impulses under generalized impulsive and switching scheme

“…The hybrid system is a kind of complex dynamic system which is composed of continuous dynamic process and discrete dynamic process and influences each other alternately and has been applied in industrial practice control, construction management (Phan et al, 2018), and physical (Kelm et al, 2021) and other fields. Nowadays, more attention has been paid to the hybrid system, including switching system and impulse system.…”
