Research on Power Control Technology for Distribution Networks Oriented towards High-Proportion Integration of Distributed Generations

With the continuous advancement of smart grid construction, the high-proportion integration of distributed generations into the power grid is inevitable in future developments. However, distributed generations exhibit intermittency and volatility, significantly impacting voltage levels, short-circuit capacity, relay protection, power supply stability, and power quality. Based on this, this paper proposes a power balance control method for distribution networks suitable for high-proportion integration of distributed generations. Considering network losses, voltage deviation, and operational costs, the objective function is established. An enhanced variant of the particle swarm optimization algorithm is utilized to solve the coordinated optimization problem of distribution network power, with step size calculation explicitly addresse in this study. Experiments confirm that the proposed algorithm exhibits enhanced effectiveness and robustness relative to other existing solution methods.
