In multi-agent active distribution networks, the information exchanges in the ADMM algorithm for the decentralized distribution-level optimal power flow (D-OPF) may expose sensitive load flows of tie-lines across adjacent agents. This may be overheard by adversarial agents for business competition. To preserve this privacy, this paper proposes a differentially private consensus ADMM (DP-C-ADMM) algorithm, which can offer a mixture solution of both realistically optimal generator outputs and obfuscated-but-feasible load flows of tie-lines. And $epsilon -$ differential privacy holds for load flows of tie-lines across agents over iterations. Case study justifies the theoretical properties of this algorithm up to specified privacy parameters.

Renewable energy sources introduce more fluctuations into the power system and bring challenges to maintain the system stability. Conventional generation units are gradually replaced and may soon become inadequate to meet the frequency regulation (FR) requirements. Consequently, demand-side resources for FR have received increasing attention. Among demand-side sources, inverter air conditioners (IACs) have huge regulation capacity and account for nearly 40% of the total power consumption in summer, while energy storage systems (ESSs) excel in rapid response and powerful ramp rate. However, the inadequate ramp speed of IACs and the insufficient regulation capacity of ESSs render them incapable of providing FR independently. To tackle this problem, this paper proposes a distributed coordinated control algorithm that allows the effective utilization of ESSs and IACs to provide FR considering the respective advantages. Firstly, an equivalent thermal energy storage model of IAC in alignment with ESS is introduced considering heterogeneous parameters. Subsequently, a coordinated control framework is proposed for heterogeneous ESSs (hetero-ESSs), which are composed of ESSs and IACs. Based on the framework, a distributed consensus algorithm is devised for hetero-ESSs, and its stability is demonstrated through the application of the Lyapunov theorem. Finally, numerical studies verify that the proposed framework can promote ESSs’ short-term ability and IACs’ long-term flexibility.
