With the increasing integration of renewable energy into power grid, traditional roles transmission and distribution networks have become less distinct at operational level. The between network planning (DNP) operation is crucial to ensure grid stability. Existing research has primarily focused on collaborative control networks, leaving a gap in integrated DNP, since few works can handle intege...

Based on a Double Deep-Q Network with deep ResNet (DDQN-ResNet), this paper proposes novel method for transmission network expansion planning (TNEP). Since TNEP is large scale and mixed-integer linear programming (MILP) problem, as the optimal constraints increase, numerical calculation heuristic learning-based methods suffer from heavy computational complexities in training. Besides, due to bl...

This paper proposes an optimal transmission expansion planning (TEP) which is based on determining share of each line in merchandizing surplus (MS) of system, determining by Independent System Operator (ISO). The more share of a line in MS of system denotes the priority of a line for expansion. The procedure of determining MS of each line in a power system is based on determining the MS share o...

The long, medium and short term planning of Hungarian backbone and Budapest trunk networks in Hungarian Telecom are based on the software package PLANET, which covers a wide range of the transmission planning activities. The paper describes the PDH and SDH network planning tools, the planning processes and the resulted networks. Main present features of Hungarian backbone and Budapest trunk net...

In recent years, significant research efforts have been devoted to the optimal planning of power systems. Substation Expansion Planning (SEP) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future load demand. The large number of design variables and combination of discr...

The temporal and spatial distribution characteristics of wind power photovoltaic output are complementary to a certain extent, which can stabilize the volatility single new energy generation extent improve ability grid absorb energy. This paper aims study joint planning method transmission network considering wind-solar time space. First, model based on time-varying Copula theory is established...

With the continuous development and construction of new power system, there would be a large number renewable energy connected to electric network in future. And uncertainty have greater impact on grid, such as excessively investment low utilization rate. In view this, this paper fully considers adjustable comprehensive resources supply load side, proposes novel transmission planning framework ...
