Solving the Optimal Power Flow Optimization problem (DC/AC), GAMS and Pyomo.

## Course Description

Optimal power flow (OPF) is a mathematical optimization problem that is used to determine the optimal operating point of a power system. The goal of OPF is to minimize the operating cost of the power system while meeting all of the system’s constraints, such as the power balance, voltage limits, and thermal limits.

OPF models can be classified into two main categories: deterministic and stochastic. Deterministic OPF models assume that the future demand and generation are known with certainty. Stochastic OPF models, on the other hand, take into account the uncertainty of future demand and generation.

The most common objective function for OPF is to minimize the operating cost of the power system. However, other objective functions can also be used, such as minimizing the emissions from the power system or maximizing the reliability of the power system.

OPF models are typically solved using numerical optimization techniques. These techniques can be divided into two main categories: deterministic and heuristic. Deterministic optimization techniques guarantee that the optimal solution will be found, but they can be computationally expensive. Heuristic optimization techniques are less computationally expensive, but they do not guarantee that the optimal solution will be found.

OPF models are an essential tool for the operation of power systems. They are used to ensure that the power system is operating in a safe and efficient manner. OPF models are also used to plan for future changes to the power system, such as the addition of new generation or transmission capacity.

Here are some of the benefits of using OPF models:

• They can help to improve the efficiency of the power system by reducing operating costs.
• They can help to improve the reliability of the power system by ensuring that the system is able to meet demand even under unexpected conditions.
• They can help to reduce emissions from the power system by optimizing the mix of generation sources.

Here are some of the challenges of using OPF models:

• The models can be computationally expensive to solve.
• The models can be sensitive to the assumptions that are made about the future demand and generation.
• The models can be difficult to interpret and explain to non-technical audiences.
