From homeowner and investor perspective, integration of renewable energy with battery energy storage system (BESS) can have economic benefits. This paper presents the results of battery control in residential microgrid system using photovoltaic (PV) distributed energy resource (DER) in residential applications in Ottawa, Ontario. The battery flow is controlled on an hourly basis to optimize the cost...
This paper discusses the development of electricity distribution network tariffs. In the paper, the present state of distribution network tariffs of small customers is discussed together with key future challenges of the distribution network business. As a potential solution to these challenges, power-based tariffs of the small customers are discussed and preliminary results of a case study are presented...
Consumer demand profiles and fluctuating renewable power generation are two main sources of uncertainty in matching demand and supply. This paper proposes a model of the electricity market that captures the uncertainties on both, the operator and the user side. The system operator (SO) implements a temporal linear pricing strategy that depends on real-time demand and renewable generation in the considered...
In energy intensive enterprises (EIE) with self generation power plant, real time electricity cost is affected by dynamic change of its power consumption and generation. Centralized power demand control is usually hard to be used in EIE due to complex constraints of production process. A rational price signal which is able to lead end users to reduce power during peak hours or shift load from peak...
In this paper, demand response management is studied in the presence of volatile renewable energy resources. The renewable energy production is modeled as a stochastic process. In this setting, consumer utility, cost of energy production, cost of energy shortfall due to the randomness in renewable energy generation are taken into account, and the maximization of the total social welfare over all possible...
Increased production of renewable energy as wind energy will give a fluctuating production which requires flexible energy storages. Heat capacity in single-family houses with electrical heating using heat pumps represents a storage which can be used to balance the electricity supply. It is assumed that electricity prices will reflect surplus or deficiency in production. A performance function describing...
In this paper a deep research is made on the application problems of marginal cost in electrical market. Beginning with the description of the origin of marginal cost in microeconomics and its introduction into power system, it derives the problems existing in current marginal cost method using for calculating power price after analyzing the application premise of both. This paper also shows that...
