Abstract
For robust monitoring, control and proper energy management of renewable energy sources (RES), wireless sensing networks (WSNs) are proved to be a vital solution. Since the power system is stepping towards the smart grid system and the use of WSNs provides numerous advantages in terms of economical, reliable and safer transmission of controlling and monitoring signals, with their low cost and easy deployment. This research proposes a new architecture for efficient monitoring, control and proper energy management of smart grid system. The architecture is evolved by taking into account the SCADA system in-conjunction with WSNs as sensor nodes. The data transmission is done though wireless link based on IEEE 802.15.4 security protocol. The WSNs are arranged in multi-hop mesh network for efficient data transmission between sensor and coordinating nodes. A new economical model based on Wireless Switch-yard System is used for integrating RES. Three different scenarios are considered, i.e., with RES, without RES and with both, RES and main grid supply for proper energy management and control strategy. A total of 10.5 kW is connected as smart home load to smart grid system. The State of Charge of battery storage system varies for maintaining the constant DC link voltage at 100 V. The efficacy of proposed model is verified through laboratory setup on Power Hardware-In-Loop system.
