Electricity price based control models for thermal storages to balance fluctuations of price have become increasingly important. A number of previous studies in the field of demand side management deal with price based load control to balance the power grid. However, inadequate attention has been paid to comfort and profitability issues of end users. Therefore, insufficient solutions towards profitability...
Large apartment buildings dated from 1960 to 1992 compose 79% of Estonian residences. Since design and construction, load profile of these buildings has changed significantly: 30–50 years ago, peak loads were much lower than today and simultaneity factor values used for in-house electrical system design were different. Implementation of demand side management (DSM) and load aggregation results in...
This paper analyzes output time-series of different small scale power generation systems such as wind and photovoltaic (PV) systems and their combinations, according to the wind and global irradiance data measured in the Tallinn-Harku Aerological Station (Estonia) and household load patterns. Renewable energy resources and energy production are reviewed and household loads and their need for stored...
This paper describes design of protection and load-priority control devices for distributed generation. Possibilities of recent energy-metering integrated circuits are utilized in system diagnostics and protection. The experimental prototype is based on sensor modules and metering IC. Modules could be integrated with converters and distribution centres for voltage quality monitoring and equipment...
The paper discusses modelling and simulation of power circuits. Models were used to study energy exchange and develop a control system, in particular for vehicles with regenerative braking capability. SIMULINK models were used in control system design, including the selection of circuit components for feedbacks of switched mode converters. Models of the supply circuit were designed as independent...
