“…The bus communication line fault is shown in Figure 1. The master / slave communication model is shown in the figure . The master-slave model is only used for network management, because only in this case can different devices really form a master-slave relationship [7] . In the master-slave model, there can only be one effective host at any time, while other nodes in the network are slaves.…”

As an important part of power grid emergency management, power communication fault emergency repair scheduling can provide decision support for emergency management. Therefore, based on the current situation of emergency repair resource allocation of power communication, a multi-point fault emergency repair scheduling algorithm considering multi group cooperation is proposed, and a joint optimization model of power communication fault emergency repair considering resource allocation and multi team cooperation mechanism is established. The blackboard information processing mode is designed, which is composed of initial layer, adaptive measure optimization layer and emergency repair plan optimization layer. It can quickly give the emergency repair resource grouping scheme and emergency repair plan after multiple failures of power communication, so as to reduce the economic loss of power failure. Simulation results show the effectiveness of the proposed method.

Solar, Wind and Their Hybridization Integration for Multi-Machine Power System Oscillation Controllers Optimization: A Review

Massive growth in global electrical energy demand has necessitated a genuine exploration and integration of solar and wind energy into the electrical power mix. This incorporation goes a long way in improving the cumulative generated power capacity of the power system. However, wind and solar photovoltaic (PV) are intermittent in nature, making the provisioning of a good maximum power tracking (MPPT) scheme necessary. Furthermore, the integration is characterized by synchronization challenges and introduces various modes of power system oscillations as it is converter-driven. This greatly affects the overall stability of the integrated power mix. Consequently, various technological models have been designed to address these challenges ranging from MPPT schemes, phase-lock loop (PLL), virtual synchronous generator (VSG), power system stabilizers (PSS), flexible AC transmission system (FACTS), coordinated control and artificial intelligence (AI). In this work, a multi-machine power system model is reviewed for integration stability studies. Various technical solutions associated with the integration are also reviewed. MPPT, PLL, VSG, PSS, FACTS, coordinated control, and various optimization technique schemes used for damping controller design are discussed.

“…The other powerful method for solving stability problem is the use of Lyapunov function which is efficiently employed along with LMI for WADC design, such that the LMI can be effective in obtaining WADC gains by adding new terms [23]. In [23,24], design of WADC is presented along with time-varying delays using LMI, but instead, the output feedback signals enter the controllers without any guarantee of Lyapunov function. In other words, there is no additional variable and cross term in their Lyapunov function structure, and the time-varying delay is replaced with its boundaries, which incurs inaccurate tracking of time-varying delay.…”

This paper proposes coordinated design of wide‐area damping controller (WADC) in the presence of renewable energy resources in a large‐scale power system. To tackle with constant and time‐varying delays in wide‐area system, a robust criterion based on H∞ has been used for the coordinated WADC design. By using an auxiliary function in Lyapunov function, conservatism of linear inequality matrix (LMI) is reduced, such that larger delay margin and larger feasibility region is obtained in the presence of delays. The wind farms here are composed of doubly‐fed induction generator (DFIG) and squirrel‐cage induction generator (SCIG), which are connected to common bus of photovoltaic (PV) system by using unified power flow controller (UPFC). Then, the renewable energy units are integrated with 10 and 16‐machine power systems. Afterwards, by identifying oscillating modes, the coordinated design of WADC is carried out for rotor‐side‐converter (RSC) in DFIG, DC/AC converter in the PV units, shunt converter (SHC) in UPFC, and power system stabilizer (PSS). Different scenarios of power system operating conditions are considered to evaluate performance of the proposed approach. The simulations in power system analysis toolbox (PSAT) and programming in MATLAB demonstrate effectiveness of the conducted method.
