“…The tariff system in (10) is based on a simple arithmetic operations of rational numbers. This is less computationally expensive than current approaches based on optimization [16][17][18][19][20][21], which are numerically implemented with iterative algorithms normally based on repetitive inverse matrix computations. In this sense, the proposed tariff system results in shorter processing time than those based on optimization programs.…”

“…However, together with the complexity of the approach, a change in the conditions (an increment in DG penetration for example) requires a new run of the algorithm and a new set of parameters. In [16], a Local Marginal Pricing (LMP) approach is extended to a tariff for the Nigerian case. As the focus is cost representativeness, the impact of a LMP formulation complexity on a distribution customer level did not capture particular attention.…”

A Simple Distribution Energy Tariff under the Penetration of DG

In a scenario where distributed generation infrastructure is increasing, the impact of that integration on electricity tariffs has captured particular attention. As the distribution sector is mainly regulated, tariff systems are defined by the authority. Then, tariffs must be simple, so the methodology, criteria, and procedures can be made public to ensure transparency and responsiveness of the customers to price signals. In the aim of simplicity, tariff systems in current practices mostly consist of volumetric charges. Hence, the reduction of the energy purchased from the distribution network jeopardizes the ability of the tariff system to ensure recovery of the total regulated costs. Although various works have captured this concern, most proposals present significant mathematical complexity, contrasting with the simplicity of current practices and limiting its regulatory applicability. This work develops a tariff system that captures the basic elements of distribution systems, trying to maintain the simplicity of current practices, ensuring recovery of the total regulated cost under the penetration of distributed generation, and incentivizing through price signals operational efficiency. A simulation will be presented to discuss numerical results.

“…In recent years, research work has been carried out on transmission network planning of the power market. In the power market, the power price is quoted by generators and users according to their generation costs and consumption benefits, which forms correct price signals and guides the optimal allocation of network resources [14,15]. Based on the game theory [16,17], the transmission network planning method considering the behavior of generators and the planning decision of the transmission network is studied.…”

Multi-Stage Transmission Network Planning Considering Transmission Congestion in the Power Market

et al. 2020

The uncertainty of generation and load increases in the transmission network in the power market. Considering the transmission congestion risk caused by various uncertainties of the transmission network, the optimal operation strategies of the transmission network under various operational scenarios are decided, aiming for the maximum of social benefit for the evaluation of the degree of scenario congestion. Then, a screening method for major congestion scenario is proposed based on the shadow price theory. With the goal of maximizing the difference between the social benefits and the investment and maintenance costs of transmission lines under major congestion scenarios, a multi-stage transmission network planning model based on major congestion scenarios is proposed to determine the configuration of transmission lines in each planning stage. In this paper, the multi-stage transmission network planning is a mixed integer linear programming problem. The DC power flow model and the commercial optimization software CPLEX are applied to solve the problem to obtain the planning scheme. The improved six-node Garver power system and the simplified 25-node power system of Zhejiang Province, China are used to verify the effectiveness of the proposed multi-stage planning model.
