Energy storage units (ESUs) including EVs and home batteries enable several\nattractive features of the modern smart grids such as effective demand response\nand reduced electric bills. However, uncoordinated charging of ESUs stresses\nthe power system. In this paper, we propose privacy-preserving and\ncollusion-resistant charging coordination centralized and decentralized schemes\nfor the smart grid. The centralized scheme is used in case of robust\ncommunication infrastructure that connects the ESUs to the utility, while the\ndecentralized scheme is useful in case of infrastructure not available or\ncostly. In the centralized scheme, each energy storage unit should acquire\nanonymous tokens from a charging controller (CC) to send multiple charging\nrequests to the CC via the aggregator. CC can use the charging requests to\nenough data to run the charging coordination scheme, but it cannot link the\ndata to particular ESUs or reveal any private information. Our centralized\nscheme uses a modified knapsack problem formulation technique to maximize the\namount of power delivered to the ESUs before the charging requests expire\nwithout exceeding the available maximum charging capacity. In the decentralized\nscheme, several ESUs run the scheme in a distributed way with no need to\naggregator or CC. One ESU is selected as a head node that should decrypt the\nciphertext of the aggregated messages of the ESUs' messages and broadcast it to\nthe community while not revealing the ESUs' individual charging demands. Then,\nESUs can coordinate charging requests based on the aggregated charging demand\nwhile not exceeding the maximum charging capacity. Extensive experiments and\nsimulations are conducted to demonstrate that our schemes are efficient and\nsecure against various attacks, and can preserve ESU owner's privacy.\n
