Algorithms of In-Station Optimization in the Simulation Model of a Hydropower Plants Cascade
2018 XIV International Scientific-Technical Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2018The paper deals with the schematic diagram of mathematical model of Pamir's electric power system where cascades of hydroelectric power stations dominate in power generation. The problem of active power flow optimization between the hydropower units is considered in detail with the help of mathematical models purposely designed to address the problem ...

Analysis on Electricity Pricing Mechanism for Cascade Hydropower Stations in China
Applied Mechanics and Materials, 2011For the large cascaded hydropower stations, an electricity pricing mechanism of cascade hydropower stations on large basins is proposed. The main idea is that the electricity generated by different hydropower stations on the same river can be sold to the Grid Corporation with the same price.

A Dynamic Game Approach for Analyzing the Coalitional Stability of Cascaded Hydropower Stations
Advanced Materials Research, 2012A game model is proposed to discuss the possible coalition structures of hydropower stations. The stable coalition structures in different contexts of electricity markets are derived on basic of numerical simulation using the raw data of three hydropower stations on the middle and lower reaches of some river in China's south-western region as a case ...

Optimal operation of cascade hydropower stations using hydrogen as storage medium
Applied Energy, 2015The use of forecast information for cascade hydropower stations is one of the effective ways to increase the electricity generation reliability and economic benefit. However, the uncertainty of forecast is high when the forecast horizon is long. It is a common practice for hydropower stations to abandon water during flood seasons due to the limited ...

Optimization Scheduling of Cascade Hydropower Stations in Energy Conservation and Emission Reduction
Advanced Materials Research, 2013Considerable water saving and electricity can be attained by optimal regulation of cascade hydropower plants, equivalent to building large and medium-sized hydropower stations without increase in investment and immigration. Thus, the optimal regulation of cascade hydropower plants has great significance on increasing the consumption ratio of fossil ...
