Smart hybrid microgrid for effective distributed renewable energy sharing of PV prosumers

Abstract

In this research article, a Distributed Energy Sharing Program (DESP) is proposed to share energy among PV prosumers in a smart hybrid microgrid (SHM), making the PV prosumer utilize the energy efficiently. The difficulties faced by the PV prosumers include the intermittent nature of Renewable Energy Sources (RESs), and PV prosumers who consume their own PV power face a power fluctuation problem. PV prosumer have one-time slot with excess PV power generation (power loss) and another slot with insufficient PV power generation (shortage). Moreover, sometimes, a total absence of PV power (affecting the prosumer day to day life). PV prosumers directly connect to the utility grid, resulting in moderate PV power selling prices, but PV prosumers purchase power from the utility grid at high prices at a time slot t. PV prosumers only earn the smallest profit under this plan. As a consequence, the DESP is proposed. SHM needs a DESP to manage the Battery Storage System (BSS) and minimize the PV prosumer electricity tariff using an internal pricing scheme to utilize RES efficiently. The Internet of Things (IoT) communicates SHM to PV prosumers or vice versa, enabling efficient and cost-effective PV energy exchange. This approach enhances PV utilization and maximizes PV prosumer’s profit through DESP.
