A Coordinated Optimal Operation of a Grid-Connected Wind-Solar Microgrid Incorporating Hybrid Energy Storage Management Systems

Abstract

The hybrid-energy storage systems (ESSs) are promising eco-friendly power converter devices used in a wide range of applications. However, their insufficient lifespan is one of the key issues by hindering their large-scale commercial application. In order to extend the lifespan of the hybrid-ESSs, the cost functions proposed in this paper include the degradation of the hydrogen devices and the battery. Indeed, this paper aims to develop a sophisticated model predictive control strategy for a grid-connected wind and solar microgrid, which includes a hydrogen-ESS, a battery-ESS, and the interaction with external consumers, e.g., battery/fuel cell electric vehicles. The integrated system requires the management of its energy production in different forms, i.e., the electric and the hydrogen ones. The proposed strategy consists of the economical and operating costs of the hybrid-ESSs, the degradation issues, and the physical and dynamic constraints of the system. The mixed-logic dynamic framework is required to model the operating modes of the hybrid-ESSs and the switches between them. The effectiveness of the controller is analyzed by numerical simulations which are conducted using solar and wind generation profiles of solar panels and wind farms located in Abu Dhabi, United Arab Emirates. Such simulations, indeed, show that the proposed strategy appropriately manages the plant by fulfilling constraints and energy requests while reducing device costs and increasing battery life.

A Review of Capacity Allocation and Control Strategies for Electric Vehicle Charging Stations with Integrated Photovoltaic and Energy Storage Systems

“…Maximum utilization of PV power and minimization of operating costs were achieved. Abdelghany et al [121] proposed a coordinated and optimized operation strategy for a grid-connected wind microgrid based on an HES. The economic cost, operational cost, and degradation issues of the ESS, as well as the physical and dynamic constraints of the system, were considered.…”

“…Moreover, an MPC technique for hybrid-ESSs has been proposed in [19] to promote the autonomy of the microgrid and achieve a rapid transition response. In [20], [21] and [22], a coordinated MPC operation of a grid-connected wind-solar microgrid paired with hybrid-ESSs has been integrated in order to maximize revenue through the electricity market and minimize the ESSs operating costs. In [23], an MPC strategy has been implemented considering the energy demand, operating costs, system performances, and devices degradations.…”

“…Among these, the DFIG stands out as a widely utilized wind turbine in practical applications [1,2]. Grid-connected wind power systems, being a relatively new type of power system, encounter fresh operational challenges stemming from their extensive use of power electronics [3][4][5]. The prevalence of issues such as low inertia and weak damping has led to several instances of instability, posing a considerable risk to the secure and stable operation of power systems [6][7][8].…”
