Energy Balance in AC Is-landed Micro-grid by Frequency Bus Signalling Method
Abstract
To keep the frequency stable and maintain stability of AC Is-landed micro-grid, power exchange among Distributed Generators (DGs), Energy Storage Systems (ESS), and loads should be balanced. Many innovative control techniques have been proposed and used for enhancing the stability of micro-grid for proper energy balance. In this paper, a self governing autonomous power control strategy based on Frequency Bus Signaling is proposed in order to achieve power management. The main objective of proposed strategy is to control the state of charge of battery reservoir limiting the voltage on its terminals by controlling the power generated by the Renewable Energy Sources (RES). The frequency of the micro-grid is used to inform the DGs to generate the power to maintain the ESS state of charge below or equal its maximum allowable limit. This method uses only local measurements for power distribution. Main power management function is implemented locally in primary level, while bounded frequency control can be achieved by using additional controller system.
