“…As shown in Figure 4, a short circuit fault occurs at the upstream protection 1 of the distributed power supply, and the distributed power supply is installed on the C bus of the feeder 2. When a short circuit fault occurs at the K1 point, the short circuit current is injected into the short circuit point by the distributed source and the system at the same time [9] . Suppose that the system potential is E1, the potential of the distributed source is E2, and the line impedance from the system to the short circuit point is Z1.…”

Different types of distributed generation have different grid-connected modes, control links and basic models, and each type has different effects on 10kV power grid, so corresponding models should be established to analyse it. This paper focuses on the research of inverter-based distributed generation, and analyses the impact of different capacity, installation position and fault location on the protection device.

“…For example, increased energy consumption due to population growth, urban development, and other similar factors lead to voltage drop in the network. Therefore, one of the solutions to compensate for this issue is the construction of transmission lines [3,4]. It is also possible that power sources are not able to meet the energy consumption that has grown, so there is a need to build new sources in the power system [3].…”

This paper presents the generation and transmission expansion planning (GTEP) in electricity and gas networks by considering their resilience against floods and earthquakes. These networks supply electricity, heat, and gas consumption energies as a multi‐carrier microgrid. The scheme is expressed in the form of bi‐level optimization, the upper level of which is the minimization of generation and transmission planning cost (total investment cost and expected operating cost) in the mentioned networks constrained to the investment budget and the planning model of the mentioned elements. Lower‐level formulation minimizes the total expected annual operating cost of these networks and the expected outage cost of electricity, heat, and gas consumers in the event of floods and earthquakes. This formulation is bound by the power flow equations of electricity and gas networks, the operation and resilience constraints of the networks, and the limitation on generation capability. In this problem, the expected energy not‐supplied and the outage cost during natural disasters are considered resilience indicators. Next, a single‐level model for the proposed design is extracted from the Karush–Kuhn–Tucker (KKT) method. The basic requirement of this method is the convexity of the lower‐level constraints. For this purpose, first, a linear approximation model is obtained for the lower‐level constraints of the problem. Furthermore, stochastic optimization is adopted to model the uncertainty of load, renewable power, and network equipment availability during floods and earthquakes. Finally, the extracted numerical results confirm the capability of the proposed scheme in improving the operation and resilience of the mentioned networks using optimal generation and transmission planning.
