Optimized Integration of Hybrid Renewable Sources with Long‐Life Battery Energy Storage in Microgrids for Peak Power Shaving and Demand Side Management under Different Tariff Scenario

Abstract

Herein, a novel cost‐effective demand side management and peak power shaving are demonstrated by optimized scheduling of renewable energy source integrated grid‐connected hybrid microgrid and vanadium redox flow battery (VRFB) storage. To promote the waste to energy for the rural and urban communities, the biogas energy source is integrated along with the combined solar photovoltaic (PV) and wind energy sources. As a long life and scalable battery storage solution, VRFB storage is adopted for peak shaving and microgrid performance reliability. Power generation from the renewable sources, VRFB charge–discharge, and grid power usage are scheduled considering two practical electricity tariff profiles, thus making the overall microgrid system operation cost‐effective and efficient. The optimized cost of energy management is determined considering the operation and maintenance cost of energy source and battery storage, grid tariff profile, and power import and export. The performance of the overall control scheme is experimentally validated by a grid‐connected hybrid microgrid consisting of 10 kWp solar PV, 1 kW wind turbine, 15 kVA biogas engine generator, and 1 kW 6 h VRFB storage. The proposed energy management scheme is scalable and a generalized one that claims to be suitable for large‐scale renewable energy integrated power systems as well.

Review of Peak Shaving Features of the Power Box

“…The results showed that the suggested idea is scalable and give advantage for large-scale renewable energy source integrated power systems. [48] Another DSM technique involving load shedding was also an initiative to initiate peak shaving [49] and manage the increase in power demand. Load shedding is performed to stabilize the magnitude of frequency and voltage by shedding some part of the loads from the power generation system to balance the load supply and demand especially during an emergency state.…”

Influence of the Intraday Electricity Market Structure on the Degradation of Li‐Ion Batteries Used to Firm Photovoltaic Production

“…[ 5 ] This production cost starts making these hybrid plants competitive when they provide grid services such as frequency and voltage control, inertia emulation, output smoothing, and peak shaving. [ 6 ] In the US market, batteries are allowed to provide these services, which are remunerated to complement the generation income. [ 7 ] The European scenario, however, is quite the opposite nowadays and still presents a variety of national and regional legislations that, combined with government auctions that tend to undervalue storage, do not favor the introduction of ESS.…”

Improved Deep Q-Network for User-Side Battery Energy Storage Charging and Discharging Strategy in Industrial Parks

“…Meanwhile, most of the existing methods have not studied the optimization of charging and discharging strategies for actual industrial electricity prices and energy storage battery operation. A novel cost-effective demand side management and peak power shaving based on vanadium redox flow battery are both demonstrated [32]. This energy management scheme is a scalable model for large-scale renewable energy integrated power systems.…”
