A mixed integer linear programming model for minimum backbone grid

Frontiers in Energy Research, 2023
Developing a minimum backbone grid in the power system planning is beneficial to improve the power system’s resilience. To obtain a minimum backbone grid, a mixed integer linear programming (MILP) model with network connectivity constraints for a minimum

A Hybrid Optimization Method Combining Network Expansion Planning and Switching State Optimization

IEEE Open Access Journal of Power and Energy, 2020
Combining switching state optimization (SSO) and network expansion planning (NEP) in AC systems results in a mixed-integer non-linear optimization problem. Two methodically different solution approaches are mathematical programming and heuristic methods.

Research on the optimal allocation method of source and storage capacity of integrated energy system considering integrated demand response

Energy Reports, 2022
The optimal allocation of energy storage capacity is an important issue for integrated energy systems (IES). To reduce the impact of volatility and intermittency of renewable energy sources, the impact of volatility needs to be smoothed out by rational ...

Multiobjective strategies in power systems planning

European Journal of Operational Research, 1983
Abstract The rapidly changing decision environment in electrical systems planning calls for a new approach in planning procedures and mathematical tools. The method proposed in this study decomposes the decision making into two strata, one at the strategy setting, the other at the project selection level.
