“…Since stability problems are mostly associated with such "weak cutsets", ensuring the dynamic stability of a distribution grid is less of an issue. Analysis of systemwide accidents and emergencies in distribution grids shows that they differ in nature from those in transmission grids [7][8][9][10][11].…”

This paper focuses on the characteristic features of distribution grids, which have the greatest impact on the stability of generators and motor loads. It shows that severe accidents in distribution and transmission grids differ in nature, starting with an overload leading to line disconnections and further evolving into a voltage collapse. It appears that where generator capacity is commensurate with the total power of motors in a grid, the motor load has a significant impact on transients. The paper discusses how asynchronous operation is triggered, progresses, and can be addressed in a grid with distributed generation (DG) facilities. It further analyzes the consequences of deep grid sectionalization and proves why grid structure needs to be optimized for further development. The paper also shows how to take into account the specifics of emergency processes (i.e., accident-associated processes) in distribution grids when integrating and operating DG facilities.

“…The adaptive control and other measures form part of a move toward the creation of active distribution networks [84]. The protection can ensure the interruption of supply is given in [85]. The current protection challenges and solutions for distributed generation penetration in the distribution system are discussed in many papers [86][87][88][89][90][91][92].…”

Wide-area protection and control (WAPAC) is a new technology in the smart grid system. The high penetration of wind farms in power systems is likely to have an adverse impact on the relay operation even if the short-circuit current in such systems decays rapidly due to crowbar resistance. By including various renewable sources, and information and communication technology components, the power grid will become more complex. Approaches based on wide-area monitoring system (WAMS) are developed to solve the current challenges of the future of high renewable resources penetration. This study provides the latest main components of the WAMS architecture and the innovation in WAPAC research development using phasor measurement units (PMUs). As the extensive article review in this area is given that show no solution until now for widearea protection in case of high wind farm penetration. A new wide-area protection based on PMUs is deployed. The main concept is based on describing by differential equations the dynamic operation of the transmission lines. In case of faults, the equations become non-linear and become difficult to be solved. This is the first time to develop such an idea to identify the protected faulted zone and guarantees sustainability for the power flow.

Wide area monitoring (WAM) offers many opportunities to improve the performance of power system protection. This paper presents some of these opportunities and the motivation for their development. This methods include monitoring the suitability of relay characteristics, supervisory control of backup protection, more adaptive and intelligent system protection and the creation of novel system integrity protection scheme. The speed of response required for primary protection means that the role WAM in enhancing protection is limited to backup and system protection. The opportunities offered by WAM for enhancing protection are attractive because of the emerging challenges faced by the modern power system protection. The increasingly variable operating conditions of power systems are making it ever more difficult to select relay characteristics that will be a suitable compromise for all loading conditions and contingencies. The maloperation of relays has contributed to the inception and evolution of 70 % of blackouts, thus the supervision of the backup protection may prove a valuable tool for preventing or limiting the scale of blackouts. The increasing interconnection and complexity of modern power systems has made them more vulnerable to wide area disturbances and this has contributed to several recent blackouts. The proper management of these wide area disturbances is beyond the scope of most of the existing protection and new, adaptive system integrity protection schemes are needed to protect power system security.
