To ensure a reliable operation, control center must use state estimation to monitor the state of the system at any time. In recent years, a new type of synchronous phasor measurement unit (PMU) is developed to replace the traditional measurement meter based on the power flow. The PMU can calculate the state of the system more quickly and accurately. It will bring a significant impact on monitoring, control, and protection of the power system. Recently, Liu et al.[1] proposed a new attack which can compromise the existing bad data detection system and arbitrarily manipulate the states of power system. To prevent such an attack, this paper proposed a new algorithm to find the best placement of PMUs. We consider two kinds of attacks, i.e. random false data injection attack and targeted false data injection attack. We verify the proposed algorithm using IEEE 14-bus and 30-bus[2].
