Plug in electric vehicles (PEVs) are innovative solution to tackle environmental issues. Effective integration of parking lots into the grid and expansion of distribution system to meet loads of these lots are two main steps towards sustainable developments. An innovative concept for integration of parking lots in distribution system planning (DSP) is presented. In the proposed approach storage capability...
Effective planning is critical to electricity industries due to its role in investment decision-making regarding generation, network and demand-side resources in complex and changing circumstances. This paper expresses the institutional arrangements in Australia's National Electricity Market (NEM) in terms of a planning model. Planning was until relatively recently performed centrally. This paper...
This paper studies the Australian market conditions and subsidies in place to promote the growth of wind power through the use of a stochastic linear programming model. This model optimizes the profit obtained for a static investment based on a variety of wind and price scenarios. It is subject to different constraints which focus on the amount of initial capital injected by an investor, selling power...
One of the most used measures for improving service reliability is distribution automation (DA). The DA technology has been widely used by different utilities for quite some time. Its applicability on the Eskom distribution network is an option but it is still in the research and development stage. This paper proposes a method for a network planning engineer to motivate the use of feeder automation...
With growing penetrations of distributed photovoltaic (PV) systems in Australian electricity networks, it is increasingly important for network planners and operators to better understand, predict and hence manage the impact of these systems throughout their networks. Time series estimates of distributed PV generation mapped to different Australian geographic regions are now being created from a sample...
The incorporation of distributed PV generation data into power system planning and operation is becoming increasingly important as penetrations of PV systems on Australian distribution networks continue to grow. However, the availability of such data is currently very limited. The APVI Live PV Map (Live Map) provides near real-time distributed PV generation estimates in 57 different regions across...
The unprecedented rise of distributed generation in Australia provides utilities with a unique opportunity to more effectively manage portions of the network as microgrids. The implementation of a utility owned and operated microgrid may offer many benefits such as the deferral of capital investments, improvement in reliability, reduction of greenhouse gas emissions and reduction in network losses...
Planning and construction of charge stations are important aspects of promoting the development of electric vehicles (EVs). Integrated with the equilibrium traffic flow, a comprehensive optimization strategy aiming at achieving siting and sizing planning of charging stations on the road network is presented in this paper. The system optimization model is used for generating and assigning the equilibrium...
This paper investigates the impacts of rooftop photovoltaic (PV) penetration as well as gas market uncertainties on the generation planning decisions. These issues are paramount in the state of Queensland in Australia that has traditionally been reliant on coal based generation. A Generation Expansion Planning problem is used to evaluate alternative generation development scenarios for Queensland...
Generation expansion planning (GEP) is becoming more complicated with the integration of renewable energy sources (RES). Using the decomposition-coordination technique, the nonlinear optimization problem of GEP is decomposed into sub-problems, whose results are coordinated to obtain the optimal GEP scheme by iteration. However, using the conventional iterative method to solve GEP is becoming more...
Asset management in electrical power distribution organizations is becoming progressively explicit. However, organizations are encountering much difficulties in outlining and institutionalizing their asset management because of the complexity of the discipline. This paper has developed a useful capability maturity model for benchmarking and improving asset management for electrical power distribution...
The penetration level of renewable energy generation has been increasing in some actual power systems, and hence introduces some new problems and even challenges for transmission system planning. In modern transmission system planning, it is necessary to consider the accommodation capability of renewable energy generation, in addition to the traditional requirement for power system reliability. Given...
Because of the constant increase of photovoltaic(PV) permeability, it is needed to configure the energy storage(ES) to reduce the instability caused by PV access of the power distribution network. So that how to configure PV and ES has become an important issue. According to timing characteristics of load and PV output under different seasons and weather conditions, the configuration model of PV and...
An approach for distribution network planning considering distributed generators(DGs) is proposed in this paper. It determines the optimal placement and capacity of distributed generators in power distribution network without considering the feeder changes and substation upgrades. The corresponding planning model is built and the particle swarm optimization with inertia weight (PSO-w) is used to solve...
