“…Furthermore, since wave forms of power components are independent of the selected qd coordinates, the proposed control is more robust to the conventionally un-modeled dynamics such as dynamic of the VSC phase locked loop system. A new methodology has been proposed for decentralized optimal power flow control for overlapping area in power systems for the enhancement of the system security [126]. Iravani et al have been presented a theoretical back ground and the methodology of development of a software tool for off-line coordination of power system controllers in either a high frequency range (5-55Hz) or a low frequency range (0.1-2Hz) [127].…”

Abstract-The integration of renewable energy sources such as wind and solar into the electric power grid is a coveted yet challenging goal. The difficulties arise from the intermittency of the sources, the required increase in transmission capacity, and the lack of coordination between control entities. In this paper, a method is developed and implemented for the optimal coordination between storage and intermittent resources in multiple control areas. The problem is formulated as a decomposed multi-step optimization problem using the Optimality Condition Decomposition method. This allows reducing the computational effort by dividing the overall optimization problem into subproblems. Simulation results show convergence to the centralized solution and provide an indication of the benefits of coordinating control areas.

“…In [26], OCD is implanted on a network of workstations considering physical constraints. References [27] and [28] apply OCD in alternating current (AC) conditions. Tie-line information such as power, price and voltage is exchanged between subsystems, which realizes system decomposition and interaction.…”

“…However, [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] are focused on coordinated optimization between TNs and subsystems are parallel to each other. So all sub optimization problems use the variables of same nature, which does not apply to coordinated scheduling problem between ADNs and TN.…”

With the large-scale development of distributed generations (DGs) and the connection into the main grid of active distribution networks (ADNs), traditional centralized dispatch of power system has encountered enormous challenge. In a bilateral electricity market, introducing ADN resources in the day-ahead generation schedule will not only enrich the dispatch patterns to the power system, but also reflect the initiative of ADNs. This paper proposes a coordinated scheduling model of power system with a plurality of ADNs based on multi-agent system where ADN agents are brought in the day-ahead market clearing. The process of market clearing and the dispatch of DGs in ADNs are independent with each other but linked together through the market clearing price (MCP) and bid volume. The optimal operating point of the whole system is achieved through multiple information exchange. In comparison with the dispatch without interaction between ADNs and the market operator (MO), the coordinated scheduling model is applied in a system with four ADNs to verify that the proposed method can improve the overall interests of ADNs. Finally, the effects of storage device and tie-line power limit are analyzed.
