Optimal Power Flow Thesis The Real Meaning Of Christmas Essay

Energy management is of prime importance for power system operators to enhance the use of the existing and new facilities, while maintaining a high level of reliability. In this thesis, we develop analytical models and efficient algorithms for energy management programs in transmission and distribution networks. We use ℓ₁-norm approximation and convex relaxation techniques to transform the problem into an SDP. We develop an algorithm to determine a near-optimal solution. We derive the sufficient conditions for zero relaxation gap and design an algorithm to obtain the global optimal solution. Subsequently, we study the security-constrained unit commitment (SCUC) problem in ac-dc grids with generation and load uncertainty.

As a strategy to deal with the intermittent RES and provide demand response benefits in smart grid, integrating energy storage in the system introduces new features to the optimal power flow (OPF) problem.

Although these decomposition algorithms are very efficient, they are offline algorithms, where the future demand information is needed.

However, this type of information is not available before the end of the whole period in reality.

The results demonstrate the capabilities of the proposed MOPSO technique to generate a set of well-distributed Pareto-optimal solutions in one single run.

In smart grid, the penetration of two-way flows of electricity and information makes it capable of integrating distributed renewable energy sources (RES) and a large number of demand side users much more effectively.
