In this paper, a framework is presented to solve the problem of multistage distribution system expansion planning in which installation and/or reinforcement of substations, feeders and distributed generation units are taken into consideration as possible solutions for system capacity expansion. The proposed formulation considers investment, operation, and outage costs of the system. The expansi...

Nowadays, one of the main techniques used in heuristic planning is the generation of a relaxed planning graph, based on a Graphplan-like expansion. Planners like FF or MIPS use this type of graphs in order to compute distance-based heuristics during the planning process. This paper presents a new approach to extend the functionality of these graphs in order to manage numeric optimization criter...

With everyday lives becoming increasingly energy intensive, the need of the hour is to plan for the growing demand for clean energy in the future. This research project anticipates a very high wind penetration future for Iowa, and with it the necessity to upgrade or build transmission to transfer the energy to load centers in the east and south. Unlike the traditional planning approach which id...

With the continuous promotion of China’s electricity market reform, introduction competition in power generation provides a new research direction for expansion planning (GEP) problem, which is great significance optimization energy structure. In context marketization, price expectation during period key factor GEP independent groups. There some literature showing that can be estimated accordin...

In recent years, incremental rate of electrical demands made many challenges for policy makers of power systems. Besides, due to economic crisis and environmental concerns about the air pollution, the new investments in thermal power generation units have experienced a noticeable reduction. For this reason, the power system operators should propose novel approaches to make a balance between inc...
