Abstract
In this paper, variables consisting of power, voltage and current in high penetration energy system are established to solve the matrix equation with energy storage access, taking the power supply of a 5-node system with 30% energy ratio wind power as an instance, the state of each node variable of the system was leveled by mean optimization method based on daily load curve, via calculating power flow, nodes voltage and current and evaluating corresponding output variable variances as evaluation index for optimization. The optimal effects of power flow, nodes voltage and current variables of the system before and after energy storage access were analyzed by simulation, and the variation and improvement of variance parameters were compared to verify the effectiveness and validation of the proposed method.
