This paper attempts to propose an optimal power management for grid connected to a piezoelectric energy harvesting with a storage system to supply street lights and traffic signals. The system includes piezoelectric energy harvesting conversion, battery bank, grid and the loads, which are composed of the street lights and traffic signals. The aim is to help intensive penetration of piezoelectric energy harvesting generated into the grid by reducing the electrical power consumption during periods of maximum demand (peak demand hours) on the power utility at the lowest cost (peak shaving service). The battery plays two roles. Firstly, it stores part of the electrical energy generated by the piezoelectric energy harvesting; and secondly; it ensures the continuity supply of power when needed during down time of the piezoelectric energy harvesting. This paper presents different mode operations based on load orientation. The optimization system is done using a simple rule based management.

In past years, cryptography has been considered a dif cult task to achieve on sensor nodes for
the Internet of Energy (IoE) owing to the resource-constrained nature of 8- and 16-bit microcontroller units
(MCUs). Previous ...
