Application Of Contract Energy Management In 4MW Distributed Photovoltaic Power Generation Project

This paper is based on the distributed 4MW photovoltaic power station of contract energy management in detail. It expounds the three kinds of contract energy management way to the energy-saving benefit sharing type, section energy guarantee, energy trusteeship in-depth. On this basis, from two aspects of the customer and energy management company economic benefit analysis model is put forward. And it analyzed based on the contract energy management of photovoltaic power station operation and design.First, based on the reality of the social background, analyzes the contract energy management related theory and its application prospects in the photovoltaic power station.Secondly, according to the specific project of the truth, for the construction of photovoltaic power station equipment selection problem in particular, Considering the economic benefit and follow-up aspects of reasons, through careful calculation and comparison, finally I select the peak power of 280 Wp photovoltaic cell components, the rated ac output power of 1000 kW inverter and SG250K3 models of junction box, the construction of economical and practical distributed photovoltaic power station.Again, according to the proposed 4MW photovoltaic power station economic cost evaluation model, light in Huludao area data as a starting point, I calculate the installed cost of photovoltaic power station, and to measure power plants over the next 25 years. I analyze the energy-saving benefit sharing type, section energy guarantee, energy costs trusteeship in three different modes of contract energy management solutions concretely.In three different energy management mode of the economic benefit as the main line, using value to optimize autonomous comprehensive evaluation method, reference to investment present value, internal rate of return, net present value, investment rate of present value model of economic benefit is evaluated.Finally, I select the optimal distributed components to build a 4MW photovoltaic power station. According to the actual data of Huludao, I calculate the cost of the economy, power, etc. Respectively, I put all the data into the three types of contract energy management mode in the economic evaluation index system:use power for the dictatorship conditions to determine the weight coefficient evaluation criteria; And establish the scope of y; which is the comprehensive evaluation value of evaluation object oi (i∈N);To calculate competitive view Ci which is the competitive strength of evaluation objects oi (i∈N);Finally, I get an evaluation matrix Y. Strives for the characteristic vector which is correspond to the biggest characteristic root of symmetric matrix YYT, then compare the vector factors, Order and compare the evaluation object(Energy-saving benefit sharing, guarantee section energy, energy costs hosting type). I choose the best contract energy management solution is energy-saving benefit sharing.
